Ars Technica: Quantum computing’s also-rans and their fatal flaws

Ars Technica: Quantum computing’s also-rans and their fatal flaws. “Last month, Google claimed to have achieved quantum supremacy—the overblown name given to the step of proving quantum computers can deliver something that a classical computer can’t. That claim is still a bit controversial, so it may yet turn out that we need a better demonstration.”

Wired: IBM Says Google’s Quantum Leap Was a Quantum Flop

Wired: IBM Says Google’s Quantum Leap Was a Quantum Flop . “Monday, Big Blue’s quantum PhDs said Google’s claim of quantum supremacy was flawed. IBM said Google had essentially rigged the race by not tapping the full power of modern supercomputers. ‘This threshold has not been met,’ IBM’s blog post says. Google declined to comment.”

CNET: Google reportedly attains ‘quantum supremacy’

CNET: Google reportedly attains ‘quantum supremacy’ . “Google has reportedly built a quantum computer more powerful than the world’s top supercomputers. A Google research paper was temporarily posted online this week, the Financial Times reported Friday, and said the quantum computer’s processor allowed a calculation to be performed in just over 3 minutes. That calculation would take 10,000 years on IBM’s Summit, the world’s most powerful commercial computer, Google reportedly said.”

Science Blog: ‘Poor Man’s Qubit’ Can Solve Quantum Problems Without Going Quantum

ScienceBlog: ‘Poor Man’s Qubit’ Can Solve Quantum Problems Without Going Quantum. “It may still be decades before quantum computers are ready to solve problems that today’s classical computers aren’t fast or efficient enough to solve, but the emerging ‘probabilistic computer’ could bridge the gap between classical and quantum computing.”

Gizmodo: You Won’t See Quantum Internet Coming

Gizmodo: You Won’t See Quantum Internet Coming. “Despite the fancy name, the ‘quantum internet’ won’t be some futuristic new way to navigate online. It won’t produce any mind-blowing new content, at least not for decades. The quantum internet will look more or less the same as the internet you’re using now, but scientists and cryptographers hope it could provide protection against not only theoretical threats but also those we haven’t dreamed up yet.”

Newswise: Dawn of the Quantum Internet, Secure Quantum Cryptography, and Harnessing Entanglement

Newswise: Dawn of the Quantum Internet, Secure Quantum Cryptography, and Harnessing Entanglement. “Quantum technologies harness the unusual properties of the atomic and subatomic world, where the rules of classical physics do not apply. Properties like entanglement – what Einstein called “spooky action at a distance” – and superposition – where a single particle can exist in multiple states at once – provide remarkable opportunities to push current communications, cryptography, and computing technologies beyond their current limitations. But, what are the latest innovations in quantum research and where are new discoveries taking us?”

Phys.org: Quantum computing with molecules for a quicker search of unsorted databases

Phys.org: Quantum computing with molecules for a quicker search of unsorted databases. “Scrapbooks or social networks are collections of mostly unsorted data. The search for single elements in very large data volumes, i.e. for the needle in the data haystack, is extremely complex for classical computers. Scientists of Karlsruhe Institute of Technology (KIT) have now quantum mechanically implemented and successfully executed Glover’s algorithm, a process for the quick finding of a search element in unsorted databases. Their results are reported in the Physical Review Letters.”
