Blueprint for fault-tolerant qubits
Building a universal quantum computer is a challenging task because of the fragility of quantum bits, or qubits for short. To deal with this problem, various types of error correction have been developed. Conventional methods do this by active correction techniques. In contrast, researchers led by Prof. David DiVincenzo from Forschungszentrum Jülich and RWTH Aachen University, together with partners from the…
How Reddit’s Co-Founder, Jim Cramer, and Wall Street Reacted to GameStop’s Surge
Friday afternoon CNBC reported that “heightened speculative trading by retail investors” (later referred to as “GameStop mania”) had “continued to unnerve the market.”
The Dow Jones Industrial average lost 620.74 points, or 2%, to 29,982.62, the first time the 30-stock gauge has closed below the 30,000 mark since Dec. 14…. The market also experienced the highest trading volume in years as the…
Apple Suspended Social Media Platform Wimkin From Its App Store
Apple “suspended” the social media platform Wimkin from its App Store, the Wall Street Journal reported on Thursday, “part of a widening crackdown by tech companies on potentially dangerous content during the presidential transition.” Long-time Slashdot reader phalse phace shares their report: Mr. Sheppard said the takedowns on the platform, which has 300,000 users and mimics some of the functions of…
Error-protected quantum bits entangled for the first time
For the first time, physicists from the University of Innsbruck have entangled two quantum bits distributed over several quantum objects and successfully transmitted their quantum properties. This marks an important milestone in the development of fault-tolerant quantum computers. The researchers published their report in Nature. …
New Train Hall Opens at Penn Station, Echoing Building’s Former Glory
The Moynihan Train Hall, with glass skylights and 92-foot-high ceilings, will open Jan. 1 as an area for Amtrak and Long Island Railroad riders. The New York Times: For more than half a century, New Yorkers have trudged through the crammed platforms, dark hallways and oppressively low ceilings of Pennsylvania Station, the busiest and perhaps most miserable train hub in North…
AWS Introduces New Chaos Engineering as a Service Offering
When large companies like Netflix or Amazon want to test the resilience of their systems, they use chaos engineering tools designed to help them simulate worst-case scenarios and find potential issues before they even happen. Today at AWS re:Invent, Amazon CTO Werner Vogels introduced the company’s Chaos Engineering as a Service offering called AWS Fault Injection Simulator. From a report: The…
Light-Based Quantum Computer Exceeds Fastest Classical Supercomputers
An anonymous reader quotes a report from Scientific American: For the first time, a quantum computer made from photons — particles of light — has outperformed even the fastest classical supercomputers. Physicists led by Chao-Yang Lu and Jian-Wei Pan of the University of Science and Technology of China (USTC) in Shanghai performed a technique called Gaussian boson sampling with their quantum…
Pirate Bay Founder Warns US Govt Against Mafia-Esque Copyright Lobby
One of the original founders of The Pirate Bay, Peter Sunde, is warning against the power American corporations have on the internet. After several copyright industry groups reported Sunde’s domain registration service Njalla to the U.S. Trade Representative (USTR), branding it a “notorious market,” Sunde wrote a letter to the USTR, not to defend Njalla but to warn against the threat…
Will Tesla Update Bring Remote Access To Car Cameras?
“Tesla’s Sentry Mode is about to bring things to a whole new level by enabling Tesla owners to remotely see what their cars can see through Autopilot cameras,” claims Electrek — citing a Twitter user named green “who has been revealing new Tesla features found in software updates.” “It’s not certain when the live camera update would arrive, provided it’s not…
