PC Gamer: IBM and Google battle for quantum supremacy in computing

PC Gamer: IBM and Google battle for quantum supremacy in computing. “This month we need to deal with a big concept: quantum supremacy. Not the story of a subatomic particle trained as the CIA’s ultimate assassin but now suffering amnesia and uncovering a conspiracy. No, it’s the idea that a quantum computer might be able to solve some task that a classical computer cannot, or at least couldn’t do within the remaining lifespan of the universe.”

Phys .org: Scientists break Google’s quantum algorithm

Phys .org: Scientists break Google’s quantum algorithm. “The celebrated approach taken by Google in QAOA has sparked vast commercial interest and ignited a global research community to explore novel applications. Yet, little is known about the ultimate performance limitations of Google’s QAOA algorithm. A team of scientists from Skoltech’s Deep Quantum Laboratory took up this contemporary challenge. The all-Skoltech team led by Prof. Jacob Biamonte discovered and quantified what appears to be a fundamental limitation in the widely adopted approach initiated by Google.”

TechCrunch: Honeywell says it will soon launch the world’s most powerful quantum computer

TechCrunch: Honeywell says it will soon launch the world’s most powerful quantum computer. “‘The best-kept secret in quantum computing.’ That’s what Cambridge Quantum Computing (CQC) CEO Ilyas Khan called Honeywell‘s efforts in building the world’s most powerful quantum computer. In a race where most of the major players are vying for attention, Honeywell has quietly worked on its efforts for the last few years (and under strict NDA’s, it seems). But today, the company announced a major breakthrough that it claims will allow it to launch the world’s most powerful quantum computer within the next three months.”

University of Notre Dame: Quantum Interest

University of Notre Dame: Quantum Interest. “Published in Switzerland in the 1970s and 1980s, Epistemological Letters was a critical venue for work that was viewed as marginal by mainstream physicists of the era — work that would later contribute to important developments in areas such as quantum computing, quantum encryption and quantum teleportation. Think a Reddit for theoretical physicists.”

Phys .org: Short story collection to entangle readers in the quantum world

Phys .org: Short story collection to entangle readers in the quantum world. “Are you ready to get entangled in the science of the very small? That’s the thread running through a new anthology, Quantum Shorts: Collected Flash Fiction Inspired by Quantum Physics. Available to download as a free e-book now, the anthology presents 37 stories shortlisted in three editions of the international Quantum Shorts competition.”

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.”
