Artificial Intelligence Predicts Acute Kidney Injury in COVID-19 Patients | The Weather Channel – Articles from The Weather Channel | weather.com -…

A new artificial-intelligence-based algorithm may help clinicians predict which patients with COVID-19 face a high risk of developing acute kidney injury (AKI) requiring dialysis, say researchers.

In a recent study, a new algorithm achieved good performance for predicting which hospitalized patients will develop acute kidney injury requiring dialysis.

"A machine learning model using admission features had a good performance for prediction of dialysis need," said study co-author Lili Chan from Mount Sinai Health System in the US.

Models like this are potentially useful for resource allocation and planning during future COVID-19 surges. We are in the process of deploying this model into our healthcare systems to help clinicians better care for their patients," Chan added.

According to the researchers, preliminary reports indicate that acute kidney injury is common in patients with COVID-19. Using data from more than 3,000 hospitalised patients with COVID-19, investigators trained a model based on machine learning, a type of artificial intelligence, to predict AKI that requires dialysis. The only information gathered within the first 48 hours of admission was included, so predictions could be made when patients were admitted.

The model demonstrated high accuracy (AUC of 0.79), and features that were important for prediction included blood levels of creatinine and potassium, age, and vital signs of heart rate and oxygen saturation.

The research is scheduled to be presented online during ASN Kidney Week 2020 Reimagined October 19-25.

Artificial intelligence and the antitrust case against Google – VentureBeat

Following the launch of investigations last year, the U.S. Department of Justice (DOJ) together with attorney generals from 11 U.S. states filed a lawsuit against Google on Tuesday alleging that the company maintains monopolies in online search and advertising, and violates laws prohibiting anticompetitive business practices.

Its the first antitrust lawsuit federal prosecutors filed against a tech company since the Department of Justice brought charges against Microsoft in the 1990s.

Back then, Google claimed Microsofts practices were anticompetitive, and yet, now, Google deploys the same playbook to sustain its own monopolies, the complaint reads. For the sake of American consumers, advertisers, and all companies now reliant on the internet economy, the time has come to stop Googles anticompetitive conduct and restore competition.

Attorneys general from no Democratic states joined the suit. State attorneys general Democrats and Republicans alike plan to continue on with their own investigations, signaling that more charges or backing from states might be on the way. Both the antitrust investigation completed by a congressional subcommittee earlier this month and the new DOJ lawsuit advocate breaking up tech companies as a potential solution.

The64-page complaint characterizes Google as a monopoly gatekeeper for the internet and spells out the reasoning behind the lawsuit in detail, documenting the companys beginning at Stanford University in the 1990s alongside deals made in the past decade with companies like Apple and Samsung to maintain Googles dominance. Also key to Googles power and plans for the future is access to personal data and artificial intelligence. In this story, we take a look at the myriad of ways in which artificial intelligence plays a role in the antitrust case against Google.

The best place to begin when examining the role AI plays in Googles antitrust case is online search, which is powered by algorithms and automated web crawlers that scour webpages for information. Personalized search results made possible by the collection of personal data started in 2009, and today Google can search for images, videos, and even songs that people hum. Google dominates the $40 billion online search industry, and that dominance acts like a self-reinforcing cycle: More data leads to more training data for algorithms, defense against competition, and more effective advertising.

General search services, search advertising, and general search text advertising require complex algorithms that are constantly learning which organic results and ads best respond to user queries; the volume, variety, and velocity of data accelerates the automated learning of search and search advertising algorithms, the complaint reads. The additional data from scale allows improved automated learning for algorithms to deliver more relevant results, particularly on fresh queries (queries seeking recent information), location-based queries (queries asking about something in the searchers vicinity), and long-tail queries (queries used infrequently).

Search is now primarily conducted on mobile devices like smartphones or tablets. To build monopolies in mobile search and create scale insurmountable to competitors, the complaint states, Google turned to exclusionary agreements with smartphone sellers like Apple and Samsung as well as revenue sharing with wireless carriers. The Apple-Google symbiosis is in fact so important that losing it is referred to as code red at Google, according to the DOJ filing. An unnamed senior Apple employee corresponding with their counterpart at Google said its Apples vision that the two companies operate as if one company. Today, Google accounts for four out of five web searches in the United States and 95% of mobile searches. Last year, Google estimated that nearly half of all search traffic originated on Apple devices, while 15-20% of Apple income came from Google.

Exclusive agreements that put Google apps on mobile devices effectively captured hundreds of millions of users. An antitrust report referenced these data advantages, stating that Googles anticompetitive conduct effectively eliminates rivals ability to build the scale necessary to compete.

In addition to the DOJ report, the antitrust report Congress released earlier this month frequently cites the network effect achieved by Big Tech companies as a significant barrier to entry for smaller businesses or startups. The incumbents have access to large data sets that give them a big advantage, especially when combined with machine learning and AI, the report reads. Companies with superior access to data can use that data to better target users or improve product quality, drawing more users and, in turn, generating more data an advantageous feedback loop.

Network effects often come up in the congressional report in reference to mobile operating systems, public cloud providers, and AI assistants like Alexa and Google Assistant, which improve their machine learning models through the collection of data like voice recordings.

One potential solution the congressional investigation suggested is better data portability to help small businesses compete with tech giants.

One part of maintaining Googles search monopoly, according to the congressional report, is control of emerging search access points. While Google searches began on desktop computers, mobile is king today, and fast emerging are devices like smartwatches, smart speakers, and IoT devices with AI assistants like Alexa, Google Assistant, and Siri. Virtual assistants are using AI to turn speech into text and predict a users intent, becoming a new battleground. An internal Google document declared voice will become the future of search.

The growth of searches via Amazon Echo devices is why a Morgan Stanley analyst previously suggested Google give everyone in the country a free speaker. In the end, he concluded, it would be cheaper for Google to give away hundreds of millions of speakers than to lose its edge to Amazon.

The scale afforded by Android and native Google apps also appears to be a key part of Google Assistants ability to understand or translate dozens of languages and collect voice data across the globe.

Search is primarily done on mobile devices today. Thats what drives the symbiotic relationship between Apple and Google, where Apple receives 20% of its total revenue from Google in exchange for making Google the de facto search engine on iOS phones, which still make up about 60% of the U.S. smartphone market.

The DOJ suit states that Google is concentrating on Google Nest IoT devices and smart speakers because internet searches will increasingly take place using voice orders. The company wants to control the next popular environment for search queries, the DOJ says, whether it be wearable devices like smartwatches or activity monitors from Fitbit, which Google announced plans to acquire roughly one year ago.

Google recognizes that its hardware products also have HUGE defensive value in virtual assistant space AND combatting query erosion in core Search business. Looking ahead to the future of search, Google sees that Alexa and others may increasingly be a substitute for Search and browsers with additional sophistication and push into screen devices,' the DOJ report reads. Google has also harmed competition by raising rivals costs and foreclosing them from effective distribution channels, such as distribution through voice assistant providers, preventing them from meaningfully challenging Googles monopoly in general search services.

In other words, only Google Assistant can get microphone access for a smartphone to respond to a wake word like Hey, Google, a tactic the complaint says handicaps rivals.

AI like Google Assistant also features prominently in the antitrust report a Democrat-led antitrust subcommittee in Congress released, which refers to AI assistants as efforts to lock consumers into information ecosystems. The easiest way to spot this lock-in is when you consider the fact that Google prioritizes YouTube, Apple wants you to use Apple Music, and Amazon wants users to subscribe to Amazon Prime Music.

The congressional report also documents the recent history of Big Tech companies acquiring startups. It alleges that in order to avoid competition from up-and-coming rivals, companies like Google have bought up startups in emerging fields like artificial intelligence and augmented reality.

If you expect a quick ruling by the DC Circuit Court in the antitrust lawsuit against Google, youll be disappointed that doesnt seem at all likely. Taking the 1970s case against IBM and the Microsoft suit in the 1990s as a guide, antitrust cases tend to take years. In fact, its not outside the realm of possibility that this case could still be happening the next time voters pick a president in 2024.

What does seem clear from language used in both US v Google and the congressional antitrust report is that both Democrats and Republicans are willing to consider separating company divisions in order to maintain competitive markets and a healthy digital economy. Whats also clear is that both the Justice Department and antitrust lawmakers in Congress see action as necessary based in part on how Google treats personal data and artificial intelligence.

Analyst Who Nailed Bitcoin Crash Says One Altcoin Set to Erupt As Analysts Refresh Bitcoin, Ethereum and XRP Forecasts – The Daily Hodl

A trader who predicted Bitcoins deep plunge to $4,000 in March says one of the years most talked-about altcoins is now ready to erupt.

The pseudonymous analyst known in the cryptoverse as Capo tells his 20,000 Twitter followers that Chainlinks (LINK) correction, which saw the coins value crash from its all-time high of $19.85 to below $9.00 from mid-August to September, might be coming to an end. According to the trader, the decentralized oracle network is in a position to parabolically rise to $31 before 2020 expires.

If you are surprised by the BTC breakout, wait for LINK to take off.

As for Bitcoin, the analyst is bullish on the leading cryptocurrency but he believes that BTC must push through a few resistance levels at around $13,000, $15,000, and $17,000 before skyrocketing.

Looking at Ethereum, Capo is extremely bullish on the leading smart contract platform.

Id buy the entire ETH supply if I could.

The crypto trader expects ETH to ignite a steep upwards movement and outperform BTC.

I have no doubt that ETH will perform better than BTC in the next bull cycle.

Capo is also keeping a close eye on the ETH/BTC pair. In a new tweet, the trader implies that ETH/BTC may have pulled off a big bear trap.

Oh boy.

Other analysts are also bullish on the worlds dominant cryptocurrency. Prominent trader Smart Contracter tells his crew of 65,000 that BTC is ready to explode to $16,000.

Still just under 2 hours to go but looks like were going to get another ripper daily close on BTC. Looking like a double extension of the wave three of this leg up is forming instead of a single extension, kind of feeling $14,000 wont prove as much of a resistance as we think.

The crypto analyst is also bullish on XRP. He says that Ripples native token is poised to follow ETHs bullish footsteps and surge close to $0.29.

Basically, XRP looks exactly like ETH did before it broke out yesterday.

Should Ethereum no longer be classified as an altcoin? – AMBCrypto English

For all its maturity over the last few years, the crypto-market, on many levels, continues to be divided along very primitive and tribal levels. Statements like Bitcoin is the best and Ethereum is the future all reek of how many see the market not as a collective whole, but as a sum of its parts. Yet another one of these petty debates was at the fore recently after Ethereums Vitalik Buterin tweeted,

As expected, most of the responses the tweet received werent very kind. In fact, any proper discourse associated with the tweet soon spilled over to become a cussing match between Bitcoin maximalists, Ethereans, and everybody else. Now, while the level of discourse might have petered out, it should be noted that Buterin raised an interesting point there. Should Ethereum no longer be classified as an alt?

Now, both of these camps often have a long list of points to shout out when such a question is posed. We shall not go there. Instead, lets keep the focus on Ethereum and its newfound and to-be-expected functionality.

Emergence as a Crypto-capital Asset

Ethereum is many things to many people, and one can argue that all of these descriptions are well-contended among many. However, one feature that doesnt get a lot of limelight is Ethers emergence as a crypto-capital asset. While this may be because Ether isnt one yet, the fact of the matter is that it can, and thats worth considering.

Think about it What is a crypto-capital asset? Well, they are tokenized assets that represent both (1) economic rights and (2) governance rights over a network or protocol. Sounds neat enough, right? Well, juxtapose that definition against our case study and everything is a little hazier.

As highlighted by Banklesss Q3 Token Report, the much-anticipated ETH2 upgrade is key to Ethers emergence as a crypto-capital asset since it will guarantee future rights to cash flows on Ethereum as holders will be able to earn transaction fees by becoming a validator and staking on the ETH network. Thats not all as under EIP1559, ETH holders will earn some margin of the revenue via fee burns whenever the network usage is high.

Now, on the face of it, the aforementioned paragraph would satisfy the economic rights aspect of a crypto-capital asset. However, it doesnt truly satisfy the governance rights aspect of the same definition. This is the reason why this section was prefaced by something along the lines of Ether is getting there

As highlighted by the aforementioned report, the fact of the matter is that even with ETH2, validators will only have soft-fork governance rights, and not actual governance rights like the ones enjoyed by MKRs token holders.

So yes, Ether may not be a crypto-capital asset yet. But, it has the potential to get there. And, recognition of that fact, recognition of its potential and multi-functionality, is crucial to understanding how an asset should be classified. Ergo, its not hard to see why Buterin feels Ethereum is more than just an ordinary alt. His sentiments were shared by Ryan Sean Adams too, who tweeted,

In fact, Buterin found an unexpected supporter in his corner a few days ago after CFTC Chair Heath Tabert commented,

If Bitcoin is email, a one-trick ponybut obviously revolutionary, Ethereum goes far beyond that, its more like the Internet.

Much ado about nothing?

No word is absolutely wrong or dirty or insulting. It all depends upon context and intention Janet Jackson

While highlighting an assets utility is well and good, doing so is often at the expense of providing an incomplete picture. What also matters, ergo, is perspective and context. Think about it How many times have our words and thoughts been misinterpreted because of a lack of perspective and context?

Buterin, it can be argued, is right in objecting to Ethereums classification as just an alt. On the other hand, it can also be contended that he isnt getting the connotations attached to the term alt/altcoin, when used in association with Ethereum.

Think about it in the most literal sense, Alt stands for Alternatives. What kind of alternatives? Well, alternative cryptocurrencies that emerged post-genesis aka post-Bitcoin. As simple as that. Contrary to what Buterin might think, most (excluding a small subset) use the terms alt and altcoins in this sense alone. There is nothing derogatory or nefarious here, and neither is the use of these terms a dig at Ethereum.

Simply put, this debate may just have been a case of much ado about nothing. Even so, perhaps, there is a lot Ethereum can cheer for, especially in light of its growing institutional adoption. Now, if only ETH 2.0 can get going sometime soon

High-Profile Crypto Trader Says Ethereum, XRP and Three Small-Cap Altcoins Set to Break Out After Bitcoins Big Move – The Daily Hodl

Top crypto strategist and trader Crypto Rand says a select number of altcoins including Ethereum (ETH) and XRP are poised to ignite bullish breakouts.

Rand tells his 220,000 Twitter followers that Ethereum, which he refers to as the money printer, is ready to launch the next leg up as it breaches the resistance of a bullish continuation pattern.

ETH wants to catch up with BTC. Bull pennant breaking out.

The trader is also looking at Ripples native asset XRP, which he thinks is primed to go above resistance at $0.28 first and then $0.33.

XRP wants to join the party. Bullish breakout.

Rand is also bullish on blockchain-based digital advertising platform Basic Attention Token (BAT). The trader expects the crypto token to surge nearly 30% to above $0.28 as BAT breaks out from a bullish reversal pattern.

BAT | Wonderful setup.

As for blockchain scalability solution Matic Network (MATIC), Rand believes that the stage is set for the low-cap altcoin to catalyze a bullish rally after MATIC took out the diagonal resistance that has kept the coin bearish since August.

MATIC | What an amazing setup!

Rand is also keeping a close watch on the decentralized finance (DeFi) darling yearn.finance (YFI).

The trader implies that the brutal correction, which sent YFI from an all-time high of $43,873 in mid-September to around $12,260 earlier this month, may have come to an end. The trader highlights the price levels of around $16,000, $20,000, and $34,000 as areas of interest for bulls.

Looks like $YFI wants to fly.

Top 3 altcoin events to happen this week – Somag News

In the coming days, there will be important developments on Wanchain (WAN), from the hard fork to the listing of Chainlink (LINK) on Bitstamp.

Bitcoin has had a good start this week as well as last week. The leading crypto currency with its market value reached $ 11,840 on the first day of the week. In addition to the rise in price, the market share of cryptocurrency has also approached 60 percent from 58 percent in the past week. As the money moved from altcoins to Bitcoin, there was a decrease in the prices of altcoins. Ether lost 2.5 percent compared to last week, while Binance Coin dropped below $ 30. The biggest decrease in the top 10 compared to last week is in Polkadot with 8.5 percent.

While the situation of the Bitcoin and altcoin markets is generally like this, it is possible to see more mobility in the prices of some altcoins with the developments that will occur in the coming days. So whats up this week? Heres what weve compiled:

Wanchain, which aims to be an infrastructure that connects the decentralized financial world, has a hard fork on Thursday. The hard fork, called Mars and will take place at 03:00 on October 22, is seen as the most important update after the Mercury hard fork in December 2019.

Zcoin (XZC), a privacy-focused crypto currency launched in 2016, experienced its first block prize halving last month, with block rewards dropping from 25 XZC to 12.5 XZC. After this big milestone, an important update is now getting closer to Zcoin.

A new privacy protocol called Lelantus to Zcoin is moving to the testnet stage today. It is stated that when Lelantus is activated in Zcoin, a high degree of anonymity, better performance will be offered in the crypto currency, and transaction sizes will decrease.

Bitstamp announced last month that it was reviewing 25 cryptocurrencies to list. One of those featured here was Chainlink (LINK). LINK, one of the biggest cryptocurrencies, will be listed on Bitstamp today. Yesterday, deposits and withdrawals for LINK were launched.

Bitstamp is a well-established cryptocurrency exchange that started operations in 2011. The Luxembourg-based exchange has reached a trading volume of $ 125 million in the last 24 hours.

Altcoin Season! Will the Gains Soar or Swing Within Same Range? – Digital Market News

More money will be made in the Alt-Season that follows

- Advertisement -

The altcoin season is when the maximum number of altcoins rally with significant gains. The top 100 cryptos are considered and more than 50 percent of the coins are required to have a bull run for a successful Altcoin Season.

In the past Altcoin season, cryptos like Maker, VeChian, Chainlink, Cardano, etc and many other rallied with an average of more than 50 percent. However, Bitcoin price was not impacted much as it was during the altcoin season, Bitcoin crossed $10000 and never looked back till now.

However, it is speculated that the crypto space may have yet another altcoin season by the end of 2020 and would be more profitable than before. One of the crypto influencer, The Crypto Dog, has predicted a probable altcoin season in the month of November 2020.

- Advertisement -

The testnet of ETH 2.0 is successfully launched and the working is been closely monitored. Once the testnet is successfully completed, ETH 2.0 phase 0 would be ready for the launch which is expected by end of 2020.

The main issue with the current Ethereum blockchain is the high gas-fees. Hence, this issue is speculated to be addressed in ETH 2.0. If in case the issue is resolved as per the expectation, then the ERC-20 tokens are expected to boom yet again with intensified growth in the DeFi space.

With the bull rally of ERC-20 tokens, Ethereum price also is expected to touch to great heights with the success of ETH2.0. Hence many predict a possible Altcoin season by the end of 2020 which can continue in early 2021 also.

Top 3 Gainers of The Week Litecoin, Chainlink, Wrapped Bitcoin: More gains ahead for these altcoins – FXStreet

The cryptocurrency market has been on fire recently. Bitcoin broke above the critical resistance of $12,000 and tested a new high of 2020, with all major altcoins following the lead.

The total capitalization of all digital assets in circulation increased to $394 billion, having gained over $40 billion in the last seven days. The market has mostly recovered from the previous week's losses incurred by the news that one of the most popular cryptocurrency exchanges, OKEx, suspended all digital assets/cryptocurrency withdrawals.

The best performers of the week are Litecoin, Chainlink, and Wrapped Bitcoin. These altcoins managed to capitalize on the crypto market recovery.

At the time of writing, LTC/USD is changing hands at $56.9. The 8th largest digital asset, with the current market capitalization of $3.2 billion, has gained over 18% in the last seven days to become the best-performing altcoin of the week out of top-50.

On the intraday charts, LTC/USD is trying to move above the local resistance line at $56.8. Once it is out of the way, the upside is likely to gain traction with the next focus on$64. This barrier limited the coin's recovery during the August consolidation pattern. A move higher will bring $69 (the highest level of 2020) and $70 into focus.

On the upside, the initial support comes at $51. This level served as a formidable resistance during the best part of September and October until it was broken on October 21 amid the strong rally across the board. A sustainable move below this area will invalidate the short-term bullish scenario and allow for a deeper decline to $45.5, followed by $41.5.

The on-chain data shows that an important resistance area is located on the approach to $60, as over 74,000 addresses holding over 2.6 million coins have their breakeven point there.

However, on the downside, the first supply area comes on approach to $54, as over 3.7 million coins were bought around this price. The next supply wall is seen around $51, which coincides with the technical barrier mentioned above.

Chainlink (LINK) is another top-performer of the week. The 6th largest digital asset has gained over 16% in the last seven days to trade at $12.30 by press time. LINK's market capitalization is registered at $4.8 billion, while its average daily trading volume is 1.47 billion, in line with the long-term figures.

On the intraday chart, LINK/USD broke above the resistance of $11.6 with the next bullish target created by a psychological $13. This barrier limited the recovery at the beginning of September andmay trigger the downside correction if the LINK's bullish trend fails to gain momentum. Once it is out of the way, the upside is likely to gain traction with the next focus on$15.6.

On the downside, the initial barrier is created by the above-mentioned $11.6 that served as channel support in September. A sustainable move below this area will trigger more sell-off to the psychological $10 and $9.70.

The data on In and Out of the Money Positioning (IOMP) confirms that there is s a strong barrier located on the approach to $13 as over 4,000 addresses holding nearly 17 million coins have their breakeven point there. Notably, there are no significant barriers above this area.

On the downside, the strongest supply zone comes on approach to $10.00.

Wrapped Bitcoins (WBTC) is a tokenized version of Bitcoin that runs on the Ethereum blockchain. Basically, it is backed by BTC, and its price is following the price of BTC, which makes it similar to a stablecoin. Currently, there are over 110 095 WBTC in circulation, while their average daily trading volume amounts to $29 billion. For the sake of comparison, Bitcoin's average trading volume comes at $27 billion.

Source: CoinMarketCap

The DeFi boom explains the growing popularity of tokenized Bitcoins as it allows BTC holders to participate in the new lucrative industry without converting their tokens into ETH or other coins.

Valuation of quantum computer maker D-Wave slashed by more than half after company struggles to raise financing – The Globe and Mail

D-Wave has fallen short of financial targets and only had a handful of buyers for its expensive, shed-sized computers.

STEPHEN LAM/REUTERS

One of Canadas most heavily funded early stage technology companies, quantum computer developer D-Wave Systems, undertook a costly refinancing this year that wiped out most of the value of some long-time investors, including the U.S. Central Intelligence Agencys venture capital arm, Amazon CEO Jeff Bezos and fund giant Fidelity Investments, according to public filings and three sources.

The US$40-million financing, including US$10-million from new investor NEC Corp., came as part of a capital restructuring that cut D-Waves valuation to less than US$170-million before the receipt of funds, down from about US$450-million, the sources familiar with the company said. The Globe and Mail is not disclosing their identities as they are not authorized to speak on the matter.

Existing investors who participated including Montreal-based Public Sector Pension Investment Board (D-Waves top shareholder, with $100-million-plus invested to date), Business Development Bank of Canada and Goldman Sachs maintained their relative stakes, limiting the writedown of their holdings. Those that didnt, including the CIAs In-Q-Tel arm, Mr. Bezos and Fidelity, saw their stakes significantly devalued, by upward of 85 per cent in some cases.

Story continues below advertisement

The funding was undertaken during a transformational year for Burnaby, B.C.-based D-Wave, the leader in a global race to develop computers whose chips draw their power by harnessing natural properties of subatomic particles to perform complex calculations faster than conventional computers.

Despite raising more than US$300-million from investors to date, D-Wave has fallen short of financial targets and only had a handful of buyers for its expensive, shed-sized computers, which were mainly used by researchers to tinker with cutting-edge technology. D-Wave has generated just more than US$75-million of customer contracts in its 21 years.

Meanwhile, newer quantum computer startups are attracting buzz and financing, while giants including IBM, Intel and Google continue to develop their own quantum computers.

This year, D-Wave promoted Silicon Valley veteran executive Alan Baratz to chief executive officer, replacing Vern Brownell, to step up efforts to commercialize its technology. It parted ways with several other top executives, including its chief financial officer and senior vice-president responsible for applications and technology. Long-time board members Steve Jurvetson, a Silicon Valley venture capitalist, and ex-Cisco executive Don Listwin also left.

Mr. Baratz has earned praise from investors for shifting D-Waves strategy away from selling computers, which listed for US$15-million, in favour of offering internet access to the machines. With the recent launch of its latest processor and updated software and service offerings, D-Wave says it can help companies solve real-world business problems and deliver business value.

The company has never looked better," said Rick Nathan, managing director with Kensington Capital Partners, a D-Wave investor. "After all this time, it now feels like [D-Wave] has achieved real product market fit and is scaling with its customers. This is new, and as a long-time investor, it is great to see.

But D-Wave is still not financially self-sustaining. It was on the verge of raising significant funds from a Chinese investor that backed out when Canadian authorities arrested a top executive of Chinas Huawei Technologies in 2018. Existing investors subsequently injected US$30-million in 2019 to tide D-Wave over, but after it struggled to find new backers other than NEC, they stepped up again at the much reduced valuation.

Story continues below advertisement

D-Wave declined to comment. But evidence of the financial hit surfaced in recent public disclosures by some investors.

Regulatory filings from PenderFund Capital Managements Working Opportunity Fund show D-Wave dropped to its 11th largest investment as of June 30 from its second-largest before. The fund didnt say why, but separately disclosed it had cut the carrying value of one of its private holdings, likely D-Wave, by $22.6-million after the unidentified company did a significant equity financing at a lower [valuation] level" than prior financings.

Fidelitys annual report shows three funds that had invested $18.3-million in D-Wave valued their combined stakes at $3.1-million as of June 30, down 85.6 per cent from a year earlier. A Fidelity spokesman declined to comment.

Meanwhile, U.S. fund manager 180 Degree Capital cut the value of its D-Wave stake to US$1.2 million from US$7.7 million on Dec. 31. The U.S. fund manager paid US$5.7-million for its stake from 2008 to 2014. In a call with 180 Degree investors on Aug. 11, president Daniel Wolfe said the writedown was directly related to a financing event that repriced the company. Also, 180 Degree further revealed that D-Wave in April consolidated all outstanding shares into one class of preferred stock in a new holding company, DWSI Holdings Inc., and completed a 1-for-5 reverse stock split.

Mr. Wolfe said D-Wave has not performed, and its value has dropped materially and that fundraising has been very difficult. Sales have been difficult. But he added he was very bullish on Mr. Baratzs ability to lead [D-Wave] to the next level.

60-year-old limit to lasers overturned by quantum researchers – Griffith News

A team of Australian quantum theorists has shown how to break a bound that had been believed, for 60 years, to fundamentally limit the coherence of lasers.

The coherence of a laser beam can be thought of as the number of photons (particles of light) emitted consecutively into the beam with the same phase (all waving together). It determines how well it can perform a wide variety of precision tasks, such as controlling all the components of a quantum computer.

Now, in a paper published inNature Physics, the researchers from Griffith University and Macquarie University have shown that new quantum technologies open the possibility of making this coherence vastly larger than was thought possible.

The conventional wisdom dates back to a famous 1958 paper by American physicists Arthur Schawlow and Charles Townes, said Professor Howard Wiseman, projectleaderand Director of Griffiths Centre for Quantum Dynamics.

Each of them went on to win a Nobel prize for their laser work.

They showed theoretically that the coherence of the beam cannot be greater than the square of the number of photons stored in the laser, he said.

But they made assumptions about how energy is added to the laser and how it is released to form the beam.

The assumptions made sense at the time, and still apply to most lasers today, but they are not required by quantum mechanics.

In our paper, we have shown that the true limit imposed by quantum mechanics is that the coherence cannot be greater than the fourth power of the number of photons stored in the laser, said Associate Professor Dominic Berry, from Macquarie University.

When the stored number of photons is large, as is typically the case, our new upper bound is much bigger than the old one.

But can this new bound on coherence be achieved?

Yes, says Dr NarimanSaadatmand, a researcher inProfessorWisemans group.

By numerical simulation we have found a quantum mechanical model for a laser which achieves the theoretical upper bound for coherence, in a beam that is otherwise indistinguishable from that of a conventional laser.

So,when we will see these new super-lasers?

Probably not for a while, says Mr Travis Baker, the PhD student on the project at Griffith University.

But we do prove that it would be possible to construct our truly quantum-limited laser using superconducting technology. This is the same technology used in the current best quantum computers, and our proposed device may have applications in that field.

Our work raises many interesting questionssuch as whether it could allow more energy-efficient lasers, Professor Wiseman said.

That would also be a great benefit, so we hope to able to investigate that in the future.
