‘This achievement is the result of years of research and the dedication of many people,’ Google engineering director Hartmut Neven said in a blog post (Bloomberg) — Alphabet Inc.’s Google said it’s built a computer that’s reached “quantum supremacy,” performing a computation in 200 seconds that would take the fastest supercomputers about 10,000 years. The […]



Google quantum computer leaves old-school supercomputers in the dust

  A new era of computing could bring about a ‘quantum apocalypse’ ‘Our modern systems of finance, commerce, communication, transportation, manufacturing, energy, government, and healthcare will for all intents and purposes cease to function,’ cyber security expert warns A new era of unfathomably fast computers is just a few years away, with quantum computers set […]



Here’s what quantum supremacy does—and doesn’t—mean for computing

September 29th, 2019 at 12:03 pm » Comments Off

Google has reportedly demonstrated for the first time that a quantum computer is capable of performing a task beyond the reach of even the most powerful conventional supercomputer in any practical time frame—a milestone known in the world of computing as “quantum supremacy.” The ominous-sounding term, which was coined by theoretical physicist John Preskill in […]



IBM’s new 53-qubit quantum ‘mainframe’ is live in the cloud

September 27th, 2019 at 1:44 am » Comments Off

IBM has boosted its growing stable of quantum computers with a new 53-quantum bit (qubit) device, the most powerful ever offered for commercial use. Google announced a more powerful 72-qubit ‘Bristlecone’ model last year, but that was for its internal techies only. IBM’s, by contrast, feels significant because it can be used by absolutely anyone […]
