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.”

Google’s claims of quantum supremacy: Groundbreaking, overhyped, or both? (Penn Today)

Penn Today: Google’s claims of quantum supremacy: Groundbreaking, overhyped, or both?. “Google’s feat of engineering, creating the first fully programmable quantum computer, has been met with both enthusiasm and skepticism. In fact, an Oct 21st pre-print by researchers at IBM claims that the computation Google said would require 10,000 years to complete could be done in only two-and-a-half days using a different approach. In this Q&A, Lee Bassett, a scientist who works on quantum computing platforms, explains the science behind the headlines, what IBM’s counterargument means, and what the future holds for this fast-growing, and incredibly hyped, field of research.”

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.”

ScienceBlog: Using Soundwaves To Search Through Big Data With More Stability And Ease. “In a paper published in Nature Research’s journal, Communications Physics, researchers in the University of Arizona Department of Materials Science and Engineering have demonstrated the possibility for acoustic waves in a classical environment to do the work of quantum information processing without the time limitations and fragility.”

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.”
