Cryptocurrencies trading | your guide in the world of trading …

CryptoCurrencies TradingCryptocurrencies is the Big thing at the moment.

It will be hard to not have heard about Bitcoin, Litecoin and Ethereum. The markets of these cryptocoins have gone through the roof and those that were early to get in are reaping now the fruits.But in order for you to do the same you need a little bit more information

Cryptography has everything to do with coding to keep data secure. This term is not something new. The cryptocurrency is a virtual or better said digital asset that utilizes cryptography as its security measure. That makes it thus saver and makes it very hard to impossible counterfeit unlike regular bills and coins.

and the most known of the first cryptocurrencies that were launched and opened the way for Crypto Currencies Trading on other cryptocoins. It was launched in 2009 by Satoshi Nakamoto, a pseudonym that could be a person or a group , there has been some debate about this and every now and then this story pops back up.

The system was open source and peer to peer. The most important aspect of this is that theres no central agency (like the government) that regulates or issues these cryptocurrencies or CryptoCurrencies Trading in general

The same fact made it also somewhat perfect for the business that were trying to keep their delaing off the books and unknown to the goverments and banks.

The difference being that cryptocurrencies have ICOs, initial coin offerings, and any entity or group is able to launch it as an investment, while regular companies have IPOs, or initial public offerings.

The Atlantic lays bare the actual problem with not having a central authority regulating these currencies. Because there are no checks and balances the way there are with IPOs, there are many scammers out there looking for fast cash. So, This brings me to the points that if you plan to invest in a cryptocoin and want to do some cryptocurrency Trading you better make sure that it is a save and sound currency with a good reputation.

What about for example CryptoCurrencies Trading in Bitcoin or Ethereum? . Are they smart investments? Since both are very popular, and areactually used as currency.

Some are, some might be and some are not.

Not the answer you were looking for ? look at it from this way

While there are people that state that investing in general is just gambling this is not really the case. Investment that are long-term. And broad investments are very different from active trading and more speculative investment, in the short term format it can go either way , like forex or retail commodity trading and cryptocurrencies trading falls into that category.

With active short term trading, you are predicting in a short term what the coin will do. This has been for many an amazing income when it comes to bitcoin , but keep in mind where there are winners there losers.

Since the prices go up and down so fast as in forex , you are able to buy bitcoin and lose money , there is no sure thing .

the price of these cryptocurrencies often swings from one extreme to another. For example inone day in June, the price of Ethereum plummeted from $US319 to $US0.1o.

This does not mean that you have to run now as the price recovered and then some. It just means that you have to be aware of the market like any day trading requires. This is not like buying Bitcoin forgetting about it and then just cash in and buy a car. You have to educate yourself, find the right broker and watch the markets and news for developments.

But as a price goes down it also can go up tremendously. This creates thou the fear of a bubble which will make the price eventually crash. People that cashed out before a crash are the lucky or well, educated ones and make enormous amounts of money.

So be aware of the risks but if you were not interested you would not be reading this. There sis money to be made in cryptocurrency trading.

That was my little moment of doom , now lets looks how it actually works

All cryptocurrencies follow the same general system.

It starts by a cryptocurrency choosing a base unit and how much that particular unit is worth when compared to other currencies (often, the U.S. dollar is used as a baseline).this would be the ICOs.

Here everyone goes about it a bit different and this often will already indicate what kind and how success full the crypto coin will be.

Keep in mind that there are sometimes very smart people behind it that try to push the envelope of what is done till that moment but in the end, the unitin one way or another relates to the value of other established currency, which is the format all currencies are following

Units of the new cryptocurrency are then created. When a transaction is made the units are carefully formed and preserved through algorithmic encryption, then linked together in enormous chains of data (term is blockchains) , where the currency can be tracked and exchanged.

This is not enough thou, as this is not secure enough it needs more information to keep it save. The currency units need to be timestamped and properly processed to make them more stable and harder to copy.

This can be done by a third party developer, but today most of the cryptocurrencies rather crowdsource the process to those with the correct hardware and software to mine the cryptocurrency.

This in essentially verifies the transaction and build its position online. This entire process is most of the times called the consensus protocols, there are some variations of this due to other currencies.

This it will make the currency very hard to duplicate and this forger it. Some say that it can be done but in general a good crypto currency has this part covered as it would be in most cases be simpler to just print fake bills.

Since the coins are only digital ( regardless of the nice bitcoin pictures ) there are some serious implications.

When last checked there are more than a thousand different cryptocurrencies and more are popping up every month.

Some of these are to be taken very serious and those in general are the ones we are looking at when talking about cryptocurrencies trading in general.

Others are more for fun experiments or for other reasons (that you have to ask those developers).

Besides Bitcoin (who remains the big leader of the pack) there are a few crypto currencies out there that you should take notice of if you are interested in cryptocurrencies trading online. I can mention them all but that would not really help you.

The main ones that I expect to become larger stronger and more mainstream or already are those things are, the litecoin, Dash, Ripple and last but not least Ethereum.

Since many of the uses are still in the shadow it is perceived as a way to stay under the radar for less kosher deals, it needs to become a legit means of payment for everyday life and business to succeed.

Japan makes waves in this direction allowing micropayments in supermarkets with some crypto currencies.

2.The pass-through problem.

Investors, that can be even you and me, need to hold onto and invest these currencies long-term if they are going to become a real force.

As long as they are used by companies as well as regular people to switch between other currencies but for the reason to only avoid paying the exchange rates it will not achieve the right reputation, this also reflects back on point one.

3. Continues Stability.

They need to be more save then regular currencies and remain this for a longer period of time. When Ethereum,was hacked which made a damage of around 50 million dollars. It hurt then entire Cryptocurrency world.

The cryptocurrency will have to be fully trusted to see real mainstream use which is currently still not the case. On the other hand, as long as governments keep on printing money whenever they need some regular currencies are not a better option just less volatile in most cases.

The thing is thou that crypto currencies will never go away, it simple cannot be erased or ignored anymore, the banks start to fear as they are losing business and some smart countries like some Scandinavian ones are integrating some cryptocurrencies in their society making it more mainstream and accepted.

In some years to come I expect that we would know any better and the trading would be like trading EUR US is now. That said Cryptocurrencies trading is exciting and with the right education, the right broker and exchange can be very profitable.

Enjoy but be smart careful and educated. Dont trade with funds you cannot spare and follow the markets.

COMODO Internet Security Download – softpedia.com

COMODO Internet Security Premium is an antivirus system that aims to protect your system, files and folders against online threats. It includes an antivirus module, combined with firewall features build an unbreakable shield.

COMODO Internet Security Premium offers to change your DNS servers to COMODO SecureDNS servers (it has a description), and to enable “Cloud Based Behavior Analysis” of unrecognized programs by submitting them to COMODO.

When the program is launched, you are welcomed by three windows. In one of them, COMODO searched for updates, another one informed us of how the firewall had detected a new private network that our PC was about to join, and another one which is the software’s interface.

Updating takes several minutes, after which COMODO runs an automatic scan on your computer (which takes a really long time, but it’s thorough). The GUI is very eye-catching and simple to follow.

COMODO seems to have a lot of features for each main function, but they are well organized. The antivirus section lets you run or schedule a scan (a full scan, on critical areas, or a spyware scan), configure the scanner settings, view antivirus events and quarantined items, but also submit suspicious files to COMODO to be further analyzed.

The firewall lets you view events and alerts that were possibly triggered by attacks on the computer, define a new trusted or blocked application, create a set of global rules, and configure various options.

Defense+ has some interesting features, such as running a program in the Sandbox (a “safe haven” for untrusted, restricted, limited or partially limited applications), adding or removing files to and from your local safe executable database, and viewing unrecognized files (which are automatically placed in the Sandbox until further notice).

Surprisingly enough, COMODO uses very little CPU and memory resources while scanning is active. But other system applications run slower.

To sum things up, COMODO Internet Security Premium is a brilliant security application, but that’s only our opinion. You have to test it for yourself.

Best Internet Security Software 2018 – The best rated …

More and more sophisticated cyber attacks have rendered antivirus-type security solutions useless. While the majority of antivirus products offer protection against various types of malware, they become pointless in the face of targeted attacks from hackers.

When that happens, Internet Security-type solutions come to save the day. These deliver complete protection from different types of cyber threats, like: spam, hacking, spyware and phishing.

Since they come with many more features than your regular antivirus software, the price of Internet security solutions is usually high. However, if you want to buy something like that, you need to consider its advantages.

Before we reveal the best Internet Security solution of 2018 for Windows 7, 8 and 10, well tell you when to even consider buying this kind of security solution instead of a regular top-rated antivirus.

Choosing antivirus software may be difficult if youre a home user. Why? Because security solutions against viruses are hard to test and compare by a regular user. Especially when the process requires a certain amount of time before reaching clear conclusions. If you are a home user, this post on the best security products might help you.

Heres when youll need an Internet Security solution:

One of the most frequent questions regarding security software applications has to do with the differences between an antivirus and a Security solution solution.

Normally, security software manufacturers create applications in a modular way. Different protection modules are either integrated or not in the suites these manufacturers offer. The rules well talk about arent found universally. Some manufacturers of antivirus solutions prefer to group the protection modules in other ways.

Generally, an antivirus keeps you safe from viruses, files infected with malware and websites affected by different types of viruses. The protection offered by an antivirus can be resumed to the three big types of threats mentioned earlier.

Internet Security software suites come with a series of bonus modules compared to what antiviruses deliver. Here are some of them:

The table below shows a comparative analysis we did between antivirus protection systems and Internet Security ones. The comparison was performed by looking at the most frequent features integrated in these security products. Sometimes, some modules are also to be found in the best antivirus suites, even if our table doesnt show this.

Attention! These modules arent available with every Internet Security solutions out there. They can vary depending on the manufacturer. Make sure to choose the security solution that works best for you when you decide to buy one.

We tested some Internet Security software solutions on different operating systems (Windows XP, Vista, Windows 7, 8 and 10) to answer the following question: Which is the best Internet Security protection suite?

In case you decide to buy or test an Internet Security solution, visit its manufacturers website and check the tables with comparative features. These show every capability each security suite has. We also recommend checking the differences between these manufacturers antivirus software versions and Internet Security versions.

Some of them have antivirus solutions with multiple interesting features. Remember this and dont necessarily rush into buying one Internet Security solution over the other. First, check whether or not the antivirus suites deliver the protection you as a user actually need.

For instance, if you dont have kids, you will never require something with parental control. Should you not have a webcam attached to your PC, the webcam protection options a security solution suite offers are pointless.

Just as in the case of the comparative analysis of antivirus solutions, identifying the best Internet Security suite took quite long. We tested well-known security solutions and the ones created by less known software manufacturers. Security companies have already launched version 2018 of their applications. The latter have already been available ever since the middle of 2017.

Robinhood trading app introduces cryptocurrency – money.cnn.com

by Anna Bahney @annabahney January 25, 2018: 1:17 PM ET

Crypto trading will initially include only bitcoin and ethereum, with more coins offered later. Beginning in February, residents in five states will be the first to be able buy and sell — California, Massachusetts, Missouri, Montana and New Hampshire — with other states following in waves until trading is available nationwide.

Starting Thursday, all users can track market data for 16 coins (including litecoin and ripple), read crypto news, and create price alerts on Robinhood.

“It is fairly obvious that people care about [cryptocurrency],” says Baiju Bhatt, co-founder and co-CEO of Robinhood. “We want to be there and help shape the way the industry goes with a better platform at a better price.”

Related: Tell me again why I shouldn’t buy bitcoin?

Cryptos can be even riskier than other investments because of extreme volatility and security risks associated with an asset in its relative infancy. But that hasn’t stopped a wave of investors looking to jump in.

Bitcoin has been the word on everyone’s lips for the past few months, as the cryptocurrency has hit record highs. It has more than doubled since October and is now trading around $11,000, though down from its high just shy of $20,000 in December.

Bitcoin is not new to Bhatt and Robinhood co-founder and co-CEO Vlad Tenev, though. They have been looking at bitcoin and cryptos for a long time, even as far back as 2010 when they were doing their own crypto mining on personal computers.

“The thing we’re seeing now, over the past year is that crypto and bitcoin are showing resiliency,” says Bhatt. “So many times people have been quick to count it out. It has gone up and gone down. Now that resiliency is something that has some real staying power.”

There’s growing demand — particularly among young people — to get in on the action.

A recent study showed that if given $5,000, 12% of Millennials would put the money into cryptocurrency over any other type of investment, according to Swell Investing. That’s compared with just 3% of those aged 45-54 and 55-64. Men were more interested than women in putting their money in crypto, with 14% of Millennial men saying they would opt for that over any other investment, compared with 9% of women.

For a company that has pegged itself as democratizing capitalism and making high-end financial products available to everyone, offering crypto is a natural fit with Robinhood’s mission, Bhatt says.

“Crypto-currencies have the potential to change how money around the world works from the ground up,” he says. “It is a shift from institutions back to the people and we want to be central in creating that change.”

And Robinhood is betting their entrance into the space will make investors more comfortable at the table.

Currently, most people buy cryptocurrencies like bitcoin and ethereum at digital exchanges like Coinbase.

Robinhood will offer easy access to funds, says Bhatt. It will make bank transfers up to $1,000 instantly available to trade crypto-currencies. Any additional funds transferred will land in your account via the normal ACH transfer system.

“The products out there now for trading crypto feel a lot more like Friendster,” says Bhatt, referencing an early social network before Facebook. “It isn’t clear which are going to emerge as the best and the way people invest in crypto today will not be the way they do in the future, but we aim to be a part of the future.”

Robinhood adds zero-fee cryptocurrency trading and tracking …

No-commission stock trading app Robinhood will let you buy and sell Bitcoin and Ethereum without any added transaction fees starting in February, compared to Coinbases 1.5 to 4 percent fees in the US. And as of today Robinhood will let all users track the price, news, and set up alerts on those and 14 other top crypto coins, including Litecoin and Ripple.

Were planning to operate this business on a break-even basis and we dont plan to profit from it for the foreseeable future says Robinhood co-founder Vlad Tenev. The value of Robinhood Crypto is in growing our customer base and better servingour existing customers.

By essentially using crypto trading as a loss leader instead of its primary business like Coinbase and other apps, Robinhood could substantially expand beyond the 3 million users it already has. Simplifying trading and tracking could bolster Bitcoin and Ethereum. And by combining it with traditional stock, ETF, and option trading in a single app, Robinhood could further legitimize the cryptocurrency craze. The two trading worlds could cross-pollinate, dragging even more people into the crypto scene.

Robinhood founders Baiju Bhatt (left) and Vladamir Tenev (right)

Many of the startups dealing in crypto are upstarts with questionable track records. But five-year-old Robinhood has raised $176 million from top investors including Andreessen Horowitz, Index, and NEA that now value the company at $1.3 billion. Theres clear long-term benefit to rolling up crypto traders and using the feature as a wedge to get them to hold money with Robinhood where it earns interest, and pay for the Robinhood Gold premium tier for $6 to $200 a month that lets them borrow between $1,000 and $50,000.

Heres how Robinhood Crypto works. You can instantly transfer up to $1000 from your connected bank account (more if you have a Gold membership), with additional funds coming over slower ACH transfer. For smaller traders, that could eliminate the annoying delays on other platforms that can make you miss a low price you want to buy up. The whole Crypto section of Robinhood is styled with an 80s Tron design to denote the 24-hour trading window, compared to its day and night themes for when traditional stock markets are open or closed.

When you place a buy or sell order, Robinhood gives you an estimated price, connects to a slew of trading venues, exchanges, and market centers to find the lowest price, and uses its economies of scale to improve to score better prices over time. To counter market volatility, Robinhood puts a collar around your trade so if it cant execute it at close to the estimated price, it waits for the price to return or lets you know.

And in case the price of a coin skyrockets or plummets, you can place limit orders to set a price where you automatically buy or sell. The full list of coins you can track is Bitcoin, Ethereum, Bitcoin Cash, Litecoin, Ripple, Ethereum Classic, Zcash, Monero, Dash, Stellar, Qtum, Bitcoin Gold, OmiseGo, NEO, Lisk, and Dogecoin.

Only BTC and ETH will be available for trading when that rolls out to waves of users starting in California, Massachusetts, Missouri, Montana, and New Hampshire in February, though more will be added. Were extremely selective about the cryptos were making available on the platform says Tenev. Were introducing those first because these are the most mature coins that people are trading these days. Multiple times people have declared them dead and theyve come back stronger than ever.

To back-up the new Robinhood Crypto feature, the company is adding new two-factor authentication options including integrations with authenticator apps to ensure people dont get their wallets stolen and dumped. There are several senior world-class people that weve hired recently that are building the system in-house says Tenev. Still, the move paints a giant target on Robinhoods back. If the company gets hacked, or individual users get robbed, it could tarnish the fintech startups reputation.

Demand for the product was clear, though. 100,000 of Robinhoods users were regularly seaching for crypto pricing and trading in its app, and 95% of those surveyed said theyd invest in cryptos if the product supported it. Robinhood even had to send a cease-and-desist to Cobinhood, a competing crypto trading app that cribbed its name and raised $10 million in an ICO.

Judging by the choices of two top startups, you could see this week as a sign of cryptocurrencys shifting purpose. Yesterday Stripe removed Bitcoin as a payment option on its platform, and now Robinhood is adopting trading. People are thinking about cryptos less from a payments standpoint and more from an assets investment standpoint Tenev explains.

Robinhood Crypto features a Tron-style 80s design motif

As for whether hes personally invested in the crypto scene, Tenev admits Im a dabbler, definitely, but I wouldnt say that its all that significant. But its a good fit for his business, which used a lean engineering team to drop stock trading fees to zero while competitors like Scottrade and E*trade can charge over $6 per trade to cover their marketing and expansive retail footprint with huge overhead. Now Robinhood has handled $100 billion in transactions, saving its users over $1 billion in fees.

[Cryptocurrency] puts power thats historically been held by financial institutions in the hands of the people. I think that lines up directly with Robinhoods mission to democratize the financial system Tenev tells me, concluding Were an established company and we can handle it. The confidence to burst into the wild west of crypto could either tank his startup with a massive security fail or greatly boost its traction by alligning with whats become a cultural phenomenon.

Disclosures: The author of this article owns small positions in Bitcoin and Ethereum, and knows Robinhoods founders from college.

Azure Search enterprise security: Data encryption and user …

Enterprise security requires a comprehensive approach for defense in depth. Effective immediately, Azure Search now supports encryption at rest for all incoming data indexed on or after January 24, 2018, in all regions and SKUs including shared (free) services. With this announcement, encryption now extends throughout the entire indexing pipeline from connection, through transmission, and down to indexed data stored in Azure Search.

At query time, you can implement user-identity access controls that trim search results of documents that the requestor is not authorized to see. Enhancements to filters enable integration with third-party authentication providers, as well as integration with Azure Active Directory.

All indexing includes encryption on the backend automatically with no measurable impact on indexing workloads or size. This applies to newly indexed documents only. For existing content, you have to re-index to gain encryption. Encryption status of any given index is not visible in the portal, nor available through the API. However, if you indexed after January 24, 2018, data is already encrypted.

In the context of Azure Search, all aspects of encryption, decryption, and key management are internal. You cannot turn it on or off, manage or substitute your own keys, or view encryption settings in the portal or programmatically. Internally, encryption is based on Azure Storage Service Encryption, using 256-bit AES encryption, one of the strongest block ciphers available.

The Era of Quantum Computing Is Here. Outlook: Cloudy …

A lot of research on the fundamentals of quantum computing has been devoted to error correction. Part of the difficulty stems from another of the key properties of quantum systems: Superpositions can only be sustained as long as you dont measure the qubits value. If you make a measurement, the superposition collapses to a definite value: 1 or 0. So how can you find out if a qubit has an error if you dont know what state it is in?

One ingenious scheme involves looking indirectly, by coupling the qubit to another ancilla qubit that doesnt take part in the calculation but that can be probed without collapsing the state of the main qubit itself. Its complicated to implement, though. Such solutions mean that, to construct a genuine logical qubit on which computation with error correction can be performed, you need many physical qubits.

How many? Quantum theorist Aln Aspuru-Guzik of Harvard University estimates that around 10,000 of todays physical qubits would be needed to make a single logical qubit a totally impractical number. If the qubits get much better, he said, this number could come down to a few thousand or even hundreds. Eisert is less pessimistic, saying that on the order of 800 physical qubits might already be enough, but even so he agrees that the overhead is heavy, and for the moment we need to find ways of coping with error-prone qubits.

An alternative to correcting errors is avoiding them or canceling out their influence: so-called error mitigation. Researchers at IBM, for example, are developing schemes for figuring out mathematically how much error is likely to have been incurred in a computation and then extrapolating the output of a computation to the zero noise limit.

Some researchers think that the problem of error correction will prove intractable and will prevent quantum computers from achieving the grand goals predicted for them. The task of creating quantum error-correcting codes is harder than the task of demonstrating quantum supremacy, said mathematician Gil Kalai of the Hebrew University of Jerusalem in Israel. And he adds that devices without error correction are computationally very primitive, and primitive-based supremacy is not possible. In other words, youll never do better than classical computers while youve still got errors.

Others believe the problem will be cracked eventually. According to Jay Gambetta, a quantum information scientist at IBMs Thomas J. Watson Research Center, Our recent experiments at IBM have demonstrated the basicelementsof quantum error correction onsmalldevices, paving the way towards larger-scaledevices where qubits canreliablystorequantum informationfor a long period of time inthepresence of noise. Even so, he admits that a universal fault-tolerant quantum computer, which has to use logical qubits, is still along way off. Such developments make Childs cautiously optimistic. Im sure well see improved experimental demonstrations of [error correction], but I think it will be quite a while before we see it used for a real computation, he said.

For the time being, quantum computers are going to be error-prone, and the question is how to live with that. At IBM, researchers are talking about approximate quantum computing as the way the field will look in the near term: finding ways of accommodating the noise.

This calls for algorithms that tolerate errors, getting the correct result despite them. Its a bit like working out the outcome of an election regardless of a few wrongly counted ballot papers. A sufficiently large and high-fidelity quantum computation should have some advantage [over a classical computation] even if it is not fully fault-tolerant, said Gambetta.

One of the most immediate error-tolerant applications seems likely to be of more value to scientists than to the world at large: to simulate stuff at the atomic level. (This, in fact, was the motivation that led Feynman to propose quantum computing in the first place.) The equations of quantum mechanics prescribe a way to calculate the properties such as stability and chemical reactivity of a molecule such as a drug. But they cant be solved classically without making lots of simplifications.

In contrast, the quantum behavior of electrons and atoms, said Childs, is relatively close to the native behavior of a quantum computer. So one could then construct an exact computer model of such a molecule. Many in the community, including me, believe that quantum chemistry and materials science will be one of the first usefulapplications of such devices, said Aspuru-Guzik, who has been at the forefront of efforts to push quantum computing in this direction.

Quantum simulations are proving their worth even on the very small quantum computers available so far. A team of researchers including Aspuru-Guzik has developed an algorithm that they call the variational quantum eigensolver (VQE), which can efficiently find the lowest-energy states of molecules even with noisy qubits. So far it can only handle very small molecules with few electrons, which classical computers can already simulate accurately. But the capabilities are getting better, as Gambetta and coworkers showed last September when they used a 6-qubit device at IBM to calculate the electronic structures of molecules, including lithium hydride and beryllium hydride. The work was a significant leap forward for the quantum regime, according to physical chemist Markus Reiher of the Swiss Federal Institute of Technology in Zurich, Switzerland. The use of the VQE for the simulation of small molecules is a great example of the possibility of near-term heuristic algorithms, said Gambetta.

But even for this application, Aspuru-Guzik confesses that logical qubits with error correction will probably be needed before quantum computers truly begin to surpass classical devices. I would be really excited when error-corrected quantum computing begins to become a reality, he said.

If we had more than 200 logical qubits, we could do things in quantum chemistry beyond standard approaches, Reiher adds. And if we had about 5,000 such qubits, then the quantum computer would be transformative in this field.

Despite the challenges of reaching those goals, the fast growth of quantum computers from 5 to 50 qubits in barely more than a year has raised hopes. But we shouldnt get too fixated on these numbers, because they tell only part of the story. What matters is not just or even mainly how many qubits you have, but how good they are, and how efficient your algorithms are.

Any quantum computation has to be completed before decoherence kicks in and scrambles the qubits. Typically, the groups of qubits assembled so far have decoherence times of a few microseconds. The number of logic operations you can carry out during that fleeting moment depends on how quickly the quantum gates can be switched if this time is too slow, it really doesnt matter how many qubits you have at your disposal. The number of gate operations needed for a calculation is called its depth: Low-depth (shallow) algorithms are more feasible than high-depth ones, but the question is whether they can be used to perform useful calculations.

Whats more, not all qubits are equally noisy. In theory it should be possible to make very low-noise qubits from so-called topological electronic states of certain materials, in which the shape of the electron states used for encoding binary information confers a kind of protection against random noise. Researchers at Microsoft, most prominently, are seeking such topological states in exotic quantum materials, but theres no guarantee that theyll be found or will be controllable.

Researchers at IBM have suggested that the power of a quantum computation on a given device be expressed as a number called the quantum volume, which bundles up all the relevant factors: number and connectivity of qubits, depth of algorithm, and other measures of the gate quality, such as noisiness. Its really this quantum volume that characterizes the power of a quantum computation, and Gambetta said that the best way forward right now is to develop quantum-computational hardware that increases the available quantum volume.

This is one reason why the much vaunted notion of quantum supremacy is more slippery than it seems. The image of a 50-qubit (or so) quantum computer outperforming a state-of-the-art supercomputer sounds alluring, but it leaves a lot of questions hanging. Outperforming for which problem? How do you know the quantum computer has got the right answer if you cant check it with a tried-and-tested classical device? And how can you be sure that the classical machine wouldnt do better if you could find the right algorithm?

So quantum supremacy is a concept to handle with care. Some researchers prefer now to talk about quantum advantage, which refers to the speedup that quantum devices offer without making definitive claims about what is best. An aversion to the word supremacy has also arisen because of the racial and political implications.

Whatever you choose to call it, a demonstration that quantum computers can do things beyond current classical means would be psychologically significant for the field. Demonstrating an unambiguous quantum advantage will be an important milestone, said Eisert it would prove that quantum computers really can extend what is technologically possible.

That might still be more of a symbolic gesture than a transformation in useful computing resources. But such things may matter, because if quantum computing is going to succeed, it wont be simply by the likes of IBM and Google suddenly offering their classy new machines for sale. Rather, itll happen through an interactive and perhaps messy collaboration between developers and users, and the skill set will evolve in the latter only if they have sufficient faith that the effort is worth it. This is why both IBM and Google are keen to make their devices available as soon as theyre ready. As well as a 16-qubit IBM Q experience offered to anyone who registers online, IBM now has a 20-qubit version for corporate clients, including JP Morgan Chase, Daimler, Honda, Samsung and the University of Oxford. Not only will that help clients discover whats in it for them; it should create a quantum-literate community of programmers who will devise resources and solve problems beyond what any individual company could muster.

For quantum computing to take traction and blossom, we must enable the world to use and to learn it, said Gambetta. This period is for the world of scientists and industry to focus on getting quantum-ready.

This is what a 50-qubit quantum computer looks like

That’s where the pumps would normally come in. From top to bottom, the system gradually cools from four Kelvin — liquid-helium temperatures — to 800 milliKelvin, 100 milliKelvin and, finally, 10 milliKelvin. Inside the canister, that’s 10 thousandths of a degree above absolute zero. The wires, meanwhile, carry RF-frequency signals down to the chip. These are then mapped onto the qubits, executing whatever program the research team wishes to run. The wiring is also designed in a way to ensure that no extraneous noise — including heat — is transported to the quantum computer chip at the bottom.

Many in the industry have suggested that a 50-qubit system could achieve “quantum supremacy.” The term refers to the moment when a quantum computer is able to outperform a traditional system or accomplish a task otherwise thought impossible. The problem, though, is that quantum computers are only compatible with certain algorithms. They’re well-suited to quantum chemistry, for instance, and material simulations. But it’s unlikely you’ll ever use a quantum computer to complete a PowerPoint presentation. “The world is not classical, it’s quantum, so if you want to simulate it you need a quantum computer,” Welser said.

Researchers have already conducted experiments with quantum computers. Scientists at IBM were able to simulate beryllium hydride (BeH2) on a seven-qubit quantum processor last September, for example. But critics want to see a quantum computer accomplish something more tangible, which is more meaningful for the everyday consumer. That day, unfortunately, could still be a long way off.

“Somewhere between 50 and 100 qubits, we’ll reach the point where we can at least say very clearly, ‘I’ve just simulated a molecule here in a few minutes time that would have taken this giant system five days to do.’ That level we’ll be at fairly rapidly. When it gets to something that the public will understand in terms of an application they would use themselves, I can’t really speculate at this point,” Welser said.
