What is Cloud Hosting and What Are the Benefits

Cloud Hosting is preferred by all the corporate giants, but if you’re new to the hosting arena, the first and foremost question popping up in your mind would definitely be – “what is cloud hosting”.Cloud hosting sites basically operate across various web servers that are interconnected, and as opposed to traditional hosting forms such as shared hosting, and dedicated hosting, data is rendered from various servers.

You pay for what you use: As your business needs fluctuate, you’ve nothing to worry about as you can change your hosting packages based on your needs, and pay only for what you use.Choice of OS:

You can choose the operating system of your choice i.e. Linux or Windows.Flexibility:

Complete server configuration controls via an API or web-based interface.Get the Best of Both Worlds:

You can enjoy the benefits of dedicated hosting, but don’t need to bear the heavy cost of dedicated hosting, if you don’t have extensive requirements.

Dedicated servers are always located in a secure and stable data center saving you from infrastructural investments. You’ve complete control over the server, and hence you can customize the performance levels of the server completely.However, in case of any mishaps, the complete set-up goes for a toss. Secondly, if your requirements grow, you need to rent/lease a bigger dedicated server and bear the higher cost.In the case of cloud hosting, you pay as you use, and you can always make changes to your requirements (which is the real beauty of cloud hosting concept!).Additionally, you can add up other servers in the network to tackle downtime, or to expand your existing bandwidth/storage space without affecting the existing set-up even for a moment. So, it’s pretty clear that one should give serious thought to shifting to cloud hosting rather than spending unnecessarily on a VPS/dedicated host unless your business really demands it.

Also Known As: cloud web hosting, cloud site hosting

Common Misspellings: clowd hosting, claud hosting

Examples: Alright, we’re done with this theoretical stuff, and definition of cloud hosting, and now you ask show me an example of cloud hosting. Well whether you know it or not, but youre pretty familiar with this one yes, we’re talking about Google!In 2009, Google rolled out the Caffeine Update as a part of which, they made a lot of infrastructural changes, and moved to a cloud-dominated hosting base.

Continuing our example of Google, whenever you perform a search, the queries run on a massive network of computers (cloud), and instead of being limited to a single server, Google doesn’t worry about the load.This gives complete flexibility of adding more systems (servers) in the network in order to cope up with the additional load (whether expected or unexpected). Therefore, one can scale up the operations many times without facing any downtime.

What is cloud hosting? – Definition from WhatIs.com

Cloud hosting is the process of outsourcing an organization’s computing and storage resources to a service provider that offers its infrastructure services in a utility model.

The cloud provider oversees the setup, cloud infrastructure, security and maintenance, while sometimes allowing clients to customize hardware and applications and scale servers online. Compute and storage resources are spread out across hundreds of virtual machines (VMs) that load balance I/O demands in a cloud infrastructure configuration.

The cloud hosting model is a cheaper alternative to the traditional dedicated server model that requires companies to build and manage their own data centers. In the traditional model, servers and storage, with dedicated hardware and virtual resources, reside on premises and can be a costly capital and operating expense for organizations.

Cloud hosting provides significant capital and operational savings to organizations because they don’t have to spend a lot on the initial upfront capital cost associated with owning and managing data centers. IT also has the ability to scale more efficiently, using and paying only for the resources they need. In addition, long-term data retention becomes a more simplified process, eliminating the costly management of disks and tape systems.

Companies using a cloud hosting service get data protection benefits such as high availability and disaster recovery. Many organizations prefer a hybrid model that mixes compute and storage resources residing on premises with compute and storage in a cloud provider’s environment.

One of the main benefits of using cloud hosting services is flexible and more cost-efficient scalability in building applications, websites and other services. Because users can scale as needed, they are charged only for the services they use and do not pay for any unused capacity. This payment system makes cloud hosting a relatively inexpensive method of storage.

But drawbacks exist. Security issues with the cloud have gained more attention as the cloud adoption rate has grown. With data leaving the company data center, organizations run the risk of intellectual property theft and loss, compliance violations, lack of oversight over rogue employees’ actions, and data breaches.

Additional aspects to consider include high availability, recovery point objective (RPO) and recovery time objective (RTO).

Cloud hosting services have fueled a rise in the infrastructure as a service (IaaS) model, in which a third-party provider offers the hardware, software, servers, storage and networking resources to a customer, typically with a pay-per-use method.

Popular cloud hosting offerings include Amazon Web Services (AWS), the Google Cloud Platform, IBM Cloud and Microsoft Azure. AWS is the dominant player in the market, offering extensive computing services and more regions and zones than other cloud providers. However, Azure and Google have gained traction in recent years.

AWS offers its Elastic Compute Cloud (EC2) to handle compute services, along with Amazon Simple Storage Service (S3) and Amazon Glacier for storage. Google offers its Google Compute Engine (GCE) and Google Cloud Storage for the enterprise. Microsoft Azure provides Azure Virtual Machines and Azure Virtual Machine Scale Sets, and its storage includes blob, file and queue storage. Its Microsoft Office 365 is a popular cloud service.

All three major public cloud providers offer products that support containers, including Amazon’s EC2 Container Service (ECS), Google’s Container Engine and Azure’s own container services.

How will cloud hosting affect your SEO campaign? | The Drum

Hosting considerations have always been a key concern for serious SEOs as several factors are known as search signals in Googles ranking algorithm. Hosting affects everything from how spiders see your site (down time) to how humans see your site (response time) and ultimately how search engines understand your site.

The impact of physical location

Physical server location has traditionally played a leading role in geo-targeting and it can have a big impact on international rankings. To put it another way, websites hosted in the UK perform better in UK search results, while websites hosted in the US perform better in US search results.

Theres a logic behind search engines giving locally hosted websites an algorithmic lift, but its proved an expensive headache for publishers. One solution is to build country-specific sites (hosted locally on local domains) and it works, but its an unwieldy approach and a drain on resources.

Cloud hosting and geo-targeting

Googles getting smarter and there are now effective ways to target international traffic with a single domain, but a single domain means a single server location and that means sites may struggle to rank overseas. But what happens if you move your hosting into the cloud?

Cloud hosting uses a network of global servers, so cloud-based sites wont have a strict geographic footprint, but thats not the same as having a footprint in the wrong place. While Googles keeping quiet on the impact that cloud hosting has on local rankings, the consensus is that it has little or no effect, and cloud hosting brings with it a host of additional SEO benefits.

Google stays ahead of the competition by serving-up the best search results and you can help them by demonstrating speed, security and reliability. Switching to the cloud is a smart move, it shows that youre taking hosting seriously, and youll be rewarded with better rankings. Its one of the reasons we cloud hosting for our clients, and weve worked hard to earn our status as a certified Microsoft Silver Partner with in-house Microsoft Azure experts.

SEO benefits of cloud hosting

SpeedLoad time is an increasingly important ranking factor thats forcing websites to become more performant. Recent Google figures show that bounce rate increases by 90% as page load time increases from 1-5 seconds. Cloud hosting spreads load, greatly speeding-up delivery, and making sure that your site doesnt get left behind.

Security Cloud hosting providers take security seriously and better protection from hackers, scrapers and malicious bots means youre less likely to get penalised in the results.

ReliabilityUptime is understandably important in SEO as sites cant be crawled if they go down, which rarely happens in the cloud. Remember that search spiders are busy bots and they wont hesitate to go away if they cant access your site and they wont be back in a hurry.

ScalabilityCloud hosting operates on a PAYG model (or rather a Pay As You Consume) so it flexes to meet demand in real time. As a result, it provides a great UX at peak periods when other hosting might fail (and we should know as were used to temporarily scaling up for phenomenal Black Friday demand). It also makes cloud hosting surprisingly affordable as you arent paying for rack space that isnt being used.

Search engine marketing professionals are paid to sweat the small stuff and because cloud hosting is such a big deal Ridgeway recommends that you head for the cloud and give your rankings a lift. As a Microsoft Silver Partner, Kentico Gold Partner and Kentico Quality Expert, the vast majority of our clients enjoy the benefits of Kenticos all in one CMS, marketing and ecommerce solution combined with the speed and flexibility of Microsoft Azure hosting.

This Startup Just Raised $21 Million To Bring Quantum …

Zapata Computing’s initial team.

Zapata Computing, a quantum computing software startup that spun out of Harvard, announced Wednesday that it has raised $21 million in a Series A round. The round was led by Prelude Ventures and Comcast Ventures, and included participation from Pillar VC, The Engine, BASF Venture Capital, Pitango Ventures and Robert Bosch Venture Capital. The raise will bring the companys total funding to about $26.45 million.

Unique among quantum computing startups, Zapata Computing isnt interested in building quantum computers. Instead, its building software applications for those systems, as well as helping large enterprises find solutions where quantum computing makes sense, no matter what hardware that customer is using.

Were creating an enterprise-hardened software platform that allows the domain experts to go as deep as they want, as well as abstract to a certain level, Zapata CEO Chris Savoie explained to me. This is not for the faint of heart. Were not out there trying to teach an undergraduate computer science major how to program a quantum computer. Were years away from that.

Zapatas focus right now is on applications where quantum computing can offer some advantages over traditional supercomputing, particularly in three key areas: simulation of chemical reactions, machine learning and optimization problems, which are of particular interest in areas like logistics and planning.

The startup was founded in 2017 and spins out of the work of Aln Aspuru-Guzik, who has been working to apply quantum computing to chemical simulations. In his lab were four postdocs, physicists Peter Johnson and Jonny Olson; computer scientist Yudong Cao; and chemist Jhonathan Romero Fontalvo. All of them were working on different applications of quantum computing, and it was their work in Aspuru-Guziks lab that grew into the basis for the company.

To run Zapata, the cofounders tapped Savoie as CEO. A serial entrepreneur and tech company executive whose PhD research had focused on molecular simulations. Apart from the companies hed previously founded, hed also worked at Verizon and Nissan. His previous startup, OLED materials company Kyulux, had licensed AI technology developed in Aspuru-Guziks lab, which began the relationship between the two.

After expressing frustration to Aspuru-Guzik over his twice-monthly commute from Boston to Japan (Which my wife said was not a tenable business plan, Savoie joked), Aspuru-Guzik invited Savoie to meet with the Zapata founding team.

They convinced me by lunchtime that there was a there there, Savoie said. And after lunch he introduced me to IBMs quantum group and a couple of other quantum groups as the CEO of Zapata Computing.

Infographic explaining Zapata’s model.

With the current round of funding, Savoie intends to position Zapata as the primary quantum software solution for large enterprises. To that end, he intends to use this infusion of capital to hire talent on both the quantum physics side and the computer science side. It will also be seeking out international talent by expanding its existing footprint in Toronto and establishing an office in Barcelona in order to attract European talent.

We want to be global, and we want to have enough gasoline in the tank to do this right and hire the right people, Savoie said.

As it works to expand its position in the market, Savoie said that hes inspired by the way Oracle initially worked with large enterprises in its early days. Zapatas revenues will be largely driven initially by consulting fees as it helps to develop unique software solutions for enterprises and trains people to use them. Its long-term goals are also inspired by OracleSavoie notes that the company wants to build out the SQL of quantum software.

Not only the language, he said. But all of the stuff that makes that work in an efficient, enterprise-hardened situation.

The Best Cloud Web Hosting Services for 2019 | PCMag.com

Beyond a Single Server

Cloud hosting is the hot darling in the web hosting space right now. This hosting category has been around for a while, but recently has really started to gain traction, even among smaller businesses. Cloud hostingwhich spreads your site across multiple serversis the most unique of all hosting types, as it lets you do many things that you could not do with the standard shared, virtual private server (VPS), dedicated, or WordPress hosting options. Let’s explore those features.

Traditional hosting sees your website leverage the power of one particular server’s CPU, RAM, storage, and data transfers. For example, shared web hosting has your website share resources with other sites that are also hosted exclusively on one server. The result is many annoying limitations in terms of power, and the inability to handle sharp traffic surges. For better service, you can pay for a virtual private server, or even a dedicated server of varying power. In all these case, you’re basically relying on one server, and that’s it. Cloud hosting, however, kicks that single-server hosting model to the curb in a marvelous manner. With cloud hosting, your website draws resources from multiple servers.

See How We Test Web Hosting Services

Cloud hosting’s use of multiple servers gives it certain advantages over traditional hosting. For example, if your website experiences a sudden traffic spike, it can pull resources from another server to prevent slow page loads or, worse, the site going down. In addition, cloud hosting makes it incredibly simple for your to scale resources up or down, as needed.

Note that there are different types of cloud hosting. Traditional web hosts, such as DreamHost and HostGator, offer cloud hosting packages that are priced similarly as their other web hosting packages (typically in the Shared or VPS range). These small business-friendly cloud hosting solutions are what we’re primarily focused on in this roundup.

Enterprise-level, infrastructure-as-a-service cloud hosting from the likes of Amazon Web Services, Microsoft Azure, and Rackspace are also available. Though these are technically cloud hosting services, they are not what’s highlighted here. For more on that flavor of expansive (and potentially more expensive!) cloud hosting, please visit our story about the best infrastructure-as-a-service solutions.

The chart above focuses on the web hosts that boast the best cloud hosting plans of all the services we’ve reviewed. Note that we are still in the process of examining cloud hosting offerings as this is a new categorywe’re definitely going to be testing more services in the coming months. Still, with the reviews we’ve done so far and lots of research, we’ve discovered what you should look for in a cloud hosting service.

Many cloud web hosts offer unlimited monthly data transfers, so other factors may help you decide which service is best for your business. That said, if you’re interested in “unlimited” anything, no matter if it’s data or storage, be sure to read the tiny print to make sure that there aren’t any surprises. In other words, make sure your definition of unlimited matches the hosting service’s definition. They can be two very different things.

Speaking of storage, we’ve discovered that cloud hosts typically offer hard drives or solid-state drives that range between 100GB and 200GB in size. That said, you’ll occasionally discover a web host that boasts unlimited storage. (Again, the usual caveats apply with regards to “unlimited” anything.) Solid-state drives are typically faster than their hard-drive-based counterparts, but are typically smaller in terms of storage capacity. If you’re looking for sheer volume, a traditional hard drive is the way to go.

When it comes to server operating systems, Linux is typically the default option. Still, some services offer Windows hosting, too. If you have specific server-side applications that require Windows, such as SQL Server or a custom application written in .NET, then you need to make sure your web host has Windows hosting.

You’ll also want a web host with responsive 24/7 customer support. Forums, knowledge bases, and tutorials are useful tools, but there’s nothing like getting another human being on the horn (or at least in a web chat) when problems arise.

Security is of utmost importance, too. If your goal is to sell products or services, you need to look into Secure Socket Layer (SSL) and Transport Layer Security (TLS). Those technologies encrypt the data that travel’s between a customer’s computer and your company’s servers to safeguard the information from people with ill intentions.

In each of our reviews, we devote an entire section to uptime, it’s so important. Simply put, if your site is down, clients or customers will be unable to find your business or access your products or services. They may find what they’re looking for elsewhere, and never return. At the very least, customers will be annoyed, and it won’t help their image of your business. Neither is a good outcome.

Three years ago, we added formal uptime monitoring to our review process, and the results show that most web hosts do an excellent job of keeping their sites up and running. If they don’t, they suffer for it in our rankings. Even if they get everything else right, sites with uptime problems aren’t eligible for top scores. All services suffer ups and downs, sometimes for reasons beyond their control. Those sites that fail to address the problem are penalized accordingly.

What Is Cloud Storage and What Are Its Advantages?

If you like being up to date with recent technology, you may have probably wondered what is cloud storage and what can it be used for? There is no easy way to describe this promising technology, as the definition constantly changes like the softwares profile.

In laymans terms, we could define cloud storage as a computing model where all the data is stored on secure or remote servers rather than on hard drives. The so-called cloud is actually an ensemble of servers that serve as hosts for the information they receive from all over the world.

In this article on what is cloud storage, we will attempt to address some of the most common questions regarding cloud storage.

Unlike traditional storage devices like hard drives or CDs, where information is stored in a physical format, all the data in the cloud is stored virtually on servers. Furthermore, you can access everything that is on the cloud from any computer thathas an internet connection.

The first major difference between cloud storage and traditional storage means is accessibility. While hard disks offer local access to information, cloud storage offers unlimited access to data, if the users can provide the necessary passkeys and if the computer has internetaccess.

Working with a cloud storage service has many advantages, as well as disadvantages. Probably the most obvious advantage that pops into mind is that you wont need to clutter up your hard drive with useless information. Furthermore, cloud storage services usually employ advanced information compression functions, which means greater indexing capability.

This, in turn, translates to faster search speeds. However, using a cloud storage service is not without disadvantages. Being a hosting entity, the cloud relies heavily on Internet connection speed.So, how does cloud storage work?

What Is Cloud Storage?

Cloud computing is an on-demand computing model which relies on a stable Internet connection to share and access data across multiple devices such as computers or smartphones.

If we took a step back to see the bigger picture, cloud computing allows users to access all the information stored in a third-party data center. This is achieved using minimal resources and minimal supervision.

Historically speaking, cloud computing, as a functional computer model, isnt that new. In fact, the so-called cloud goes all the way back to the 70s and 80s, when ARPANET and CNET, the predecessors of the modern Internet were already hinting at what cloud storage was going to become.

Best Cloud Storage Providers

Now, the most popular cloud storage services are arguably Dropbox, OneDrive and Google Drive. Each offers similar, but slightly different services, which makes it hard to assess which is the best cloud service. Dropbox offers 2GB free cloud storage, while OneDrive offers 5GB cloud storage for free in their Basic Plan. Google Drives cloud storage free plan offers 15GB. We reviewed the best cloud storage providers, so you can take a look at our assessments below:

The best cloud storage free plans are offered by MEGA (50 GB free cloud storage), pCloud (10 GB of free online storage), and MediaFire (10 GB cloud storage free). We reviewed all 3 providers, so you can find out more about their services from our reviews:

Other good free cloud storage providers areGoogle Drive (15GB for free), Box, (10GB free cloud storage), OneDrive (5GB free cloud storage), Amazon Drive (5GB and unlimited photos with Prime).

There are also other services which are very similar to cloud computing models:

Types of Cloud Storage

Now that weve briefly talked about what is cloud storage, lets take a closer look at the classification of cloud storage service. As the need for cloud-based solutions increased, so has the nature of the service become more complex.

Presently, we can discuss four major types of cloud storage services: private, public, hybrid and mobile cloud storage services.

Private clouds are tailored to accommodate and handle data requests from small home-based companies or larger companies. Typically, this type of cloud service is the best solution for a company that wants to migrate all data by employing the services of a third-party cloud provider.

Alternately, cloud service clients can opt for two types of private clouds. An on-premise cloud uses a server or a machine that can be found in the same building. This server hosts the cloud. The other option is externally-hosted cloud storage. The host server is not in the same building as the company.

On-premise private clouds are easier to supervise. The machine that handles all the requests is in the same building as the company. Thus, the staff can easily check if something goes wrong. However, keep in mind that this type of service is better suited for bigger companies. For smaller businesses, it may be a bit pricey, as the maintenance costs can be quite high.

With public cloud, you wont need to concern about maintenance or data security, since all the data is externalized. Public clouds are easier to access and maintain than private clouds.

Furthermore, anyone having the right credentials can submit access to the cloud, from either a computer terminal connected to the Internet or from other devices such as a tablet or a smartphone.

A hybrid cloud combines some of the features of private and public clouds. One of the greatest advantages of using hybrid clouds is the greater number of customization options. You can add, delete or edit the current applications running on your cloud.

If you wish to share sensitive information, you can always opt for the private cloud feature with better security. Alternately, you can migrate some of your non-sensitive data on the public side of the cloud.

4. Mobile Cloud Storage

Mobile cloud storage allows users to store and manage files, photos, music, and videos from their mobile devices (laptops, tablets and smartphones). Many new mobile phones come with preloaded and configured cloud storage that can be used to back up the devices files. iOS devices use iCloud, Apples mobile cloud storage service. Android-operating devices use Google Drive, while Samsung Galaxy has a partnership with Dropbox. We compared the features of iCloud vs Dropbox, so you can learn more from our extensive review:

Related:ICloud Vs Dropbox Cloud Storage Comparison

5 Advantages of Cloud Storage

Below we highlight 5 obvious benefits of cloud storage:

Companies and individuals using cloud-based services are more likely to cut back on operating costs than those who still use in-house hosting solutions or external hard drives. Furthermore, according to the recent online polls on cloud storage, the average cost of one gigabyte of storage space is around 3 cents.

Consider migrating your data to a third-party cloud storage service to avoid cluttering and to ease operations.

As we mentioned in our introductory remarks, you can access all files, folder, photos, and videos in the cloud from anywhere in the world. Of course, provided you have the necessary credentials and internet access.

One of the greatest advantages of using cloud storage is that youll always have a backup solution in case something goes wrong. If something happens to the files on a computer, you can always access the cloud and retrieve any data that may have been damaged or lost.

If youve committed any changes to one or more files, the cloud will automatically sync the changes across all affiliated devices.

Most cloud storage providers tend to add extra layers of security protocols. They do this in order to prevent your files and folders from either ending up in the wrong hands or from being lost.

5 Disadvantages of Using Cloud Storage

Below we outline some of the weaknesses of cloud storage:

Since cloud-based solutions depend on the speed of your Internet upload and download speed, having a low latency can impede you from accessing the data in real time. Also, there are still many areas around the globe where you cant connect to the Internet.

For a corporation or a small business, cloud storage services are sound solutions. However, for home devices, these costs may be too high to handle.

Although the goal of cloud-based services is to minimize our dependency on physical storage devices, a large number of businesscloud storage services require the presence of a physical hard drive as well.

Customer support is not one of the stronger points of cloud storage vendors. Cloud storage providers usually instruct clients to take a closer look at the FAQ or follow online forums.

After migrating the data to a third-party cloud storage provider, there is a bit of an issue concerning who owns the information. Is it the company, as a client, or the cloud storage provider?

What is cloud storage? Its a new concept in cloud computing models that allows faster information deployment, little management, and little supervision. There are of course advantages and disadvantages for opting for this kind of services. Its up to you to figure out whether its worth it or not.

Nowadays, however, most large cloud storage providers have a diverse offer when it comes to storage plans and pricing. Plans and offers vary from provider to provider. However, most include at least some service packages for home use, as well as cloud storage plans for small businesses or large corporations. What is your experience with cloud storage?

Scientists and researchers have long extolled the extraordinary potential capabilities of universal quantum computers, like simulating physical and natural processes or breaking cryptographic codes in practical time frames. Yet important developments in the technologythe ability to fabricate the necessary number of high-quality qubits (the basic units of quantum information) and gates (elementary operations between qubits)is most likely still decades away.

However, there is a class of quantum devicesones that currently existthat could address otherwise intractable problems much sooner than that. These near-term quantum devices, coined Noisy Intermediate-Scale Quantum (NISQ) by Caltech professor John Preskill, are single-purpose, highly imperfect, and modestly sized.

Dr. Anton Toutov is the cofounder and chief science officer of Fuzionaire and holds a PhD in organic chemistry from Caltech. You can follow him at @AntonToutov.

Dr. Prineha Narang is an assistant professor of computational materials science at the John A. Paulson School of Engineering and Applied Sciences at Harvard University. You can follow her @NarangLab.

As the name implies, NISQ devices are noisy, meaning that the results of calculations have errors, which in some cases can overwhelm any useful signal.

Why is a noisy, single-purpose, 50- to few-hundred-qubit quantum device exciting, and what can we do with it in the next five to 10 years? NISQs provide the near-term possibility of simulating systems that are so mathematically complex that conventional computers cannot practically be used. And chemical systems definitely fit that bill. In fact, chemistry could be a perfect fit for NISQ computation, especially because errors in molecular simulations may translate into physical features.

To understand this, its valuable to consider what noise is and how it occurs. Noise arises because physical and natural systems do not exist in isolationthey are part of a larger environment, which has many particles, each of which are moving in different (and unknown) directions. This randomness, when discussing chemical reactions and materials, creates thermal fluctuations. When dealing with measurement and computing, this is referred to as noise, which manifests itself as errors in calculations. NISQ devices themselves are very sensitive to their external environment, and noise is already naturally present in qubit operations. For many applications of quantum devices, such as cryptography, this noise can be a tremendous limitation and lead to unacceptable levels of error.

However, for chemistry simulations, the noise would be representative of the physical environment in which both the chemical system (e.g., a molecule) and the quantum device exist. This means that NISQ simulation of a molecule will be noisy, but this noise actually tells you something valuable about how the molecule is behaving in its natural environment.

With errors as features, we may not need to wait until qubits are hyperprecise in order to start simulating chemistry with quantum devices.

Perhaps the most immediate application for near-term quantum computers is the discovery of new materials for electronics. In practice, however, this research is often done with little or no computer-based optimization and design. This is because it is too hard to simulate these materials using classical computers (except in very idealized scenarios, such as when there is only a single electron moving in the whole material). The difficulty comes from the fact that the electrical properties of materials are governed by the laws of quantum physics, which contain equations that are extremely hard to solve. A quantum computer doesnt have this problemby definition the qubits already know how to follow the laws of quantum physicsand the application of NISQs to the discovery of electronic materials is an important research direction in the Narang lab.

What is special about electronic materials is that they are usually crystalline, meaning that atoms are laid out in an organized, repeating pattern. Because the material looks the same everywhere, we dont need to keep track of all atoms, but only of a few representative ones. This means that even a computer with a modest number of qubits may be able to simulate some of these systems, opening up opportunities for highly efficient solar panels, faster computers, and more sensitive thermal cameras.

Chemical research has been going on for centuries, yet new chemistry is most typically discovered by intuition and experimentation. An application of quantum devices in which we are particularly interested at Fuzionaire is the simulation of chemical processes and catalysts, which are substances that accelerate chemical reactions in remarkable ways. Catalysts are at the heart of the entire chemical industry and are relied on each day in the production of medicines, materials, cosmetics, fragrances, fuels, and other products. Significant challenges exist, but this area is a very important opportunity for NISQ devices in the next five to 10 years.

For example, the Haber-Bosch synthesis (HB) is an industrial chemical process that turns hydrogen (H2) and nitrogen (N2) into ammonia (NH3). HB makes it possible to produce enough ammonia-based fertilizer to feed the world, but the process is energy-intensive, consuming approximately 1 to 2 percent of global energy and generating about 3 percent of total global CO2 emissions.

At the heart of the entire process is a catalyst based on iron, which is only active at high temperatures and without which the process fails. Scientists have been trying to discover new catalysts for HB that would make the chemistry more efficient, less energy-intensive, and less environmentally damaging. However, the catalyst discovery and testing process is challenging, painstaking, and costly. Despite many decades of tremendous effort by chemists and engineers, the iron catalyst discovered over 100 years ago remains the industrial state-of-the-art.

Near-term NISQ systems would be used to give chemists unprecedented insights into the inner workings of the current iron catalyst in its physical environment and would be applied to simulate novel, viable catalyst architectures, including those based on elements other than iron.

Biological systems are extraordinarily complex, which makes modeling and simulation very challenging. Prediction of biological molecules and biochemical interactions with conventional computers, especially in biologically relevant environments, becomes difficult or impossible. This forces even basic, earliest-stage biomedical research to be done by working with chemicals, cells, and animals in a lab and hoping for reproducible conditions between experiments and organisms. This is why drug discovery, a vital area of biomedical innovation that encompasses both chemistry and biology, is such a tantalizing opportunity for NISQ intervention.

Developing new medicines for cancer, neurodegenerative diseases, viruses, diabetes, and heart disease is one of the most important activities within the entire chemistry enterprise. However, the current reality is that bringing a new drug to market continues to be slow and costly, to the tune of about 10 to 15 years and more than $2 billion, by some estimates.

A central challenge within the drug discovery process is to identify a biological target that has relevance to human disease and to design molecules that could inhibit that target with the hope that this would treat the disease. Quantum devices could be used to simulate common biological targets such as kinases, G-protein-coupled receptors (GPCRs), and nuclear receptors in their dynamic environments and in complex with inhibitor molecules. These simulations would enable drug discovery scientists to identify potentially active molecules early in the process and discard non-actives from consideration. The most promising drug candidate molecules would then be synthesized and promoted to biological studies (e.g., pharmacology, toxicology) in the laboratory.

While there are great opportunities for near-term quantum devices and much hope for improved systems in the future, we must not get carried away. Research will need to solve significant challenges, including creating systems with many more qubits, improving qubit performance, and developing coding languages for quantum computers, among others.

Nevertheless, there are great reasons to be optimistic as we look forward to the next five to 10 years. Significant resources are being committed by large companies like IBM, Google, and Microsoft to quantum computing efforts; healthy investment is flowing into quantum hardware startup companies like Rigetti, D-Wave, IonQ, and others; and important academic results are being reported using current or near-term quantum devices, including solving lattice protein folding problems, predicting the optical response of exotic materials, investigating the mechanism of nitrogen fixation by nitrogenase, and many others.

As a professional chemist and physicist, were excited about the current capabilities and optimistic about the utility of near-term quantum devices. Were hopeful that these systems will provide to the scientific community new insights that will accelerate discovery and help us solve problems to improve the human condition.

What Is a Quantum Computer? | JSTOR Daily

For decades, we have been hearing about the incredible potential of quantum computers. Now, researchers claim to have turned back time inside a quantum machine. These devices, which currently exist only as prototypes, have the potential to be much faster than any current computer. But what is a quantum computer?

Rather than microchips and circuits, quantum computing relies on the principles of quantum mechanics. In particular it relies on so-called quantum entanglement, or the ability of one subatomic particle to influence a different subatomic particle some distance away. The influence is virtually instantaneous, hence the potential for computing speed.

Robert F. Service writes in Science thatquantum computers, just like regular computers, store information as 0s and 1s, known as bits. A principle of quantum mechanics, however, is that subatomic particles exist in all possible conditions, or states, simultaneously. The particle only settles on a state once it is observed. Since the particles transmitting the information have multiple states at once, quantum bits (qubits) can be both partially 0 and partially 1 simultaneously. These weird hybrid bits can basically take on any percentage value between 0 and 1 at any time. Effectively, a quantum computer calculates all possible outcomes of a calculation at once. With such power, it wont take many bits for a quantum computer to be able to calculate just about anything.

A few problems remain. For one thing, the multiple states and entanglement between particles are fragile, so the qubits can easily fall apart in a process called decoherence. To guard against decoherence, extra qubits are needed as a backup. According to science reporterCharles Q. Choi in ASEE Prism, the physics of quantum computing are well understood. The issue is actually building a machine that can manipulate not just qubits but multiple qubits connected by networks of circuits called quantum logic gates. Engineers have tried a few different approaches, including using lasers, ionized particles trapped by magnetic fields, and superconductors. Despite years of trying, however, nobody has built a quantum computer where qubits have lasted longer than a second or two. Stringing qubits together or connecting them to a regular computer that can process the information into a useable output have also proven difficult.

Despite the engineering challenges, some are confident that a working quantum computer will indeed be reality. Given the high cost and energy requirements, however, it is unlikely that quantum computers are coming soon to a desktop near you.
