Microsoft-Led Team Retracts Disputed Quantum-Computing Paper

Slashdot - 1 hour 13 min ago
A Microsoft-led team of physicists has retracted a high-profile 2018 paper that the company touted as a key breakthrough in the creation of a practical quantum computer, a device that promises vast new computing power by tapping quantum mechanics. From a report: The retracted paper came from a lab headed by Microsoft physicist Leo Kouwenhoven at Delft University of Technology in the Netherlands. It claimed to have found evidence of Majorana particles, long-theorized but never conclusively detected. The elusive entities are at the heart of Microsoft's approach to quantum computing hardware, which lags behind that of others such as IBM and Google. WIRED reported last month that other physicists had questioned the discovery after receiving fuller data from the Delft team. Sergey Frolov, from the University of Pittsburgh, and Vincent Mourik, at University of New South Wales, in Australia, said it appeared that data that cast doubt on the Majorana claim was withheld. Monday, the original authors published a retraction note in the prestigious journal Nature, which published the earlier paper, admitting the whistleblowers were right. Data was "unnecessarily corrected," it says. The note also says that repeating the experiment revealed a miscalibration error that skewed all the original data, making the Majorana sighting a mirage. "We apologize to the community for insufficient scientific rigor in our original manuscript," the researchers wrote. Frolov and Mourik's concerns also triggered an investigation at Delft, which Monday released a report from four physicists not involved in the project. It concludes that the researchers did not intend to mislead but were "caught up in the excitement of the moment," and selected data that fit their own hopes for a major discovery. The report sums up that breach of the norms of the scientific method with a quote from physics Nobel laureate Richard Feynman: "The first principle is that you must not fool yourself -- and you are the easiest person to fool." The Delft lab released raw data from its 2018 experiment Monday. Frolov and Mourik say that it should also release full data from its Majorana hunting project going back until 2010 for others to analyze.

Popular YouTubers Are Building Their Own Sites

Slashdot - 1 hour 53 min ago
An anonymous reader shares a report: Whether he's showing off astronomically expensive computer gaming hardware or dumpster-diving for the cheapest PC builds possible, Linus Sebastian's videos always strike a chord, and have made him one of the most popular tech personalities on YouTube. But Google-owned YouTube gets most episodes of Linus Tech Tips a week late. Now, they debut on his own site called Floatplane, which attracts a much smaller crowd. "Google has been very, very good to me," Linus says. "But it's a lot of eggs in one basket." And with a staff of two dozen, he cannot rely on the company to continue being what he calls his "benevolent overlord". He is not the only YouTube star looking for alternatives. For a long time there have been tensions between those creating content on YouTube and the company providing the platform, ranging from disputes about ad revenue, to copyright problems, and even rows about the way videos are recommended to people. Many successful YouTubers are now sizeable companies in their own right, and are seeking to safeguard their futures. For the last few years, Linus and co-worker Luke Lafreniere have been investing in their own platform called Floatplane. The pair stress that it is not -- and never will be -- a YouTube competitor. But they hope to provide a platform for existing video creators with a loyal audience, who might be willing to pay a few dollars a month to directly support the video-makers they love.

Manchin's filibuster reform opposition cracks a bit. Biden's friend Clyburn can blow it wide open

Daily Kos - 2 hours 10 min ago

Republican Sen. Lisa Murkowski proved Saturday just how important filibuster reform is going to be for anything else that is good to happen in this country. She offered an amendment to the American Rescue Plan that directs $800 million to services for homeless children. It was adopted by a voice vote, and everyone applauded and congratulated each other and was happy. Then they came to the final vote on passage of the bill, and Murkowski voted "no." She voted against her own amendment and against helping homeless kids. That's where bipartisanship gets you.

Significantly, following that vote and the final passage of the whole COVID-19 relief bill, the guy who most endangered passage of the plan at the very end was preening Democratic Sen. Joe Manchin. Following an entire day of negotiating and pleading and Manchin ultimately backing down, the recalcitrant West Virginian appeared on no fewer than four Sunday shows and backed down some more. His longstanding opposition to eliminating the filibuster has cracked, and he's now willing to say that it could change: "If you want to make it a little bit more painful, make them stand there and talk, I'm willing to look at any way we can." That's what he told NBC's Chuck Todd. He told Fox News' Chris Wallace essentially the same thing—that the filibuster "should be painful if you want to use it."

Saudi Arabia's Bold Plan To Rule the $700 Billion Hydrogen Market

Slashdot - 2 hours 33 min ago
The kingdom is building a $5 billion plant to make green fuel for export and lessen the country's dependence on petrodollars. From a report: Sun-scorched expanses and steady Red Sea breezes make the northwest tip of Saudi Arabia prime real estate for what the kingdom hopes will become a global hub for green hydrogen. As governments and industries seek less-polluting alternatives to hydrocarbons, the world's biggest crude exporter doesn't want to cede the burgeoning hydrogen business to China, Europe or Australia and lose a potentially massive source of income. So it's building a $5 billion plant powered entirely by sun and wind that will be among the world's biggest green hydrogen makers when it opens in the planned megacity of Neom in 2025. The task of turning a patch of desert the size of Belgium into a metropolis powered by renewable energy falls to Peter Terium, the former chief executive officer of RWE AG, Germany's biggest utility, and clean-energy spinoff Innogy SE. His performance will help determine whether a country dependent on petrodollars can transition into a supplier of non-polluting fuels. "There's nothing I've ever seen or heard of this dimension or challenge," Terium said. "I've been spending the last two years wrapping my mind around 'from scratch,' and now we're very much in execution mode." Hydrogen is morphing from a niche power source -- used in zeppelins, rockets and nuclear weapons == into big business, with the European Union alone committing $500 billion to scale up its infrastructure. Huge obstacles remain to the gas becoming a major part of the energy transition, and skeptics point to Saudi Arabia's weak track record so far capitalizing on what should be a competitive edge in the renewables business, especially solar, where there are many plans but few operational projects. But countries are jostling for position in a future global market, and hydrogen experts list the kingdom as one to watch. The U.K. is hosting 10 projects to heat buildings with the gas, China is deploying fuel-cell buses and commercial vehicles, and Japan is planning to use the gas in steelmaking. U.S. presidential climate envoy John Kerry urged the domestic oil and gas industry to embrace hydrogen's "huge opportunities." That should mean plenty of potential customers for the plant called Helios Green Fuels. Saudi Arabia is setting its sights on becoming the world's largest supplier of hydrogen -- a market that BloombergNEF estimates could be worth as much as $700 billion by 2050. "You're seeing a more diversified portfolio of energy exports that is more resilient," said Shihab Elborai, a Dubai-based partner at consultant Strategy&. "It's diversified against any uncertainties in the rate and timing of the energy transition." Blueprints are being drawn and strategies are being announced, but it's still early days for the industry. Hydrogen is expensive to make without expelling greenhouse gases, difficult to store and highly combustible. Green hydrogen is produced by using renewable energy rather than fossil fuels. The current cost of producing a kilogram is a little under $5, according to the International Renewable Energy Agency.

'Were willing to put their lives on the line': House bill blocks deportation of military veterans

Daily Kos - 3 hours 27 min ago

House Democratic legislators including the chair of the chamber’s Veterans’ Affairs committee have reintroduced legislation that would block the deportation of noncitizen U.S. military veterans, and allow eligible deported veterans to return home to the U.S. Because federal immigration officials don’t follow even their own policy, it’s unknown exactly how many veterans have been kicked out of the U.S. over the years. Advocates have estimated the number to be around 230.

“It’s a disgrace that veterans are falling through the cracks of our broken immigration system and being deported,” Veterans’ Affairs chair Mark Takano said, who reintroduced the bill with fellow Californian Juan Vargas and Arizona’s Raúl Grijalva. “Deported veterans are exiled from the country that they call home and that they fought to defend, and they face significant barriers to access the benefits they are entitled to and eligible for under the law. Congress must act and fix this injustice, and passing this comprehensive legislative package can help us achieve that.”

Fully Vaccinated Individuals Can Socialize Without Masks, Distancing, CDC Says

Slashdot - 3 hours 33 min ago
schwit1 writes: Americans who have received the full COVID-19 vaccine can gather with vaccinated grandparents or friends without wearing masks or keeping their distance, according to new CDC guidance announced Monday, and those grandparents can visit with and hug family members that aren't vaccinated as long as they don't have underlying medical conditions that put them at high risk for COVID-19. The new guidance also says that vaccinated individuals don't need to quarantine or get tested if they come in contact with someone positive for COVID-19 and don't have any symptoms.

DARPA Taps Intel To Help Build the Holy Grail of Encryption

Slashdot - 4 hours 13 min ago
The Defense Advanced Research Projects Agency, or DARPA, has signed an agreement with Intel to add it to its Data Protection in Virtual Environments project, which aims to create a practically useful form of fully homomorphic encryption. From a report: Fully homomorphic encryption has been described as the "holy grail" of encryption because it allows encrypted data to be used without ever having to decrypt it. Fully homomorphic encryption isn't fantasy -- it already exists and is usable, but it is incredibly impractical. "FHE adoption in the industry has been slow because processing data using fully homomorphic encryption methods on cryptograms is data intensive and incurs a huge 'performance tax' even for simple operations," Intel said in a press release. The potential benefits of fully homomorphic encryption make creating a practical way to use it a cybersecurity imperative. Intel succinctly describes the biggest problem in data security as being caused by "encryption techniques [that] require that data be decrypted for processing. It is during this decrypted state that data can become more vulnerable for misuse." The goal of the Data Protection in Virtual Environments program is to develop an accelerator for fully homomorphic encryption that will make it more practical and scalable, which is where Intel comes in. The chip manufacturer's role in the project will be academic research and the development of an application-specific integrated circuit that will accelerate fully homomorphic encryption processing. Intel said that, when fully realized, its accelerator chip could reduce processing times by five orders of magnitude over existing CPU-driven fully homomorphic encryption systems.
