Inside the race to build the best quantum computer on Earth

March 9th, 2020 at 12:10 pm » Comments Off

IBM thinks quantum supremacy is not the milestone we should care about. Google’s most advanced computer isn’t at the company’s headquarters in Mountain View, California, nor anywhere in the febrile sprawl of Silicon Valley. It’s a few hours’ drive south in Santa Barbara, in a flat, soulless office park inhabited mostly by technology firms you’ve […]



Quantum researchers able to split one photon into three

March 8th, 2020 at 10:06 am » Comments Off

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo report the first occurrence of directly splitting one photon into three.  The occurrence, the first of its kind, used the spontaneous parametric down-conversion method (SPDC) in quantum optics and created what quantum optics researchers call a non-Gaussian state of light. A non-Gaussian […]



Writing a quantum algorithm? Avoid using a quantum computer

February 28th, 2020 at 1:30 am » Comments Off

A Zapata researcher works on one of the company’s quantum computing algorithms. Startups are helping companies write software for quantum computers. It isn’t easy. Zapata Computing, a 30-person startup in Boston, creates software for quantum computers. But when a customer has a problem it would like to solve, one of Zapata’s first steps is to […]



Engineers just built an impressively stable quantum silicon chip from artificial atoms

February 19th, 2020 at 12:38 pm » Comments Off

Newly created artificial atoms on a silicon chip could become the new basis for quantum computing. Engineers in Australia have found a way to make these artificial atoms more stable, which in turn could produce more consistent quantum bits, or qubits – the basic units of information in a quantum system. The research builds on […]



A game plan for quantum computing

February 15th, 2020 at 12:37 pm » Comments Off

Pharmaceutical companies have an abiding interest in enzymes. These proteins catalyze all kinds of biochemical interactions, often by targeting a single type of molecule with great precision. Harnessing the power of enzymes may help alleviate the major diseases of our time. Unfortunately, we don’t know the exact molecular structure of most enzymes. In principle, chemists […]



Quantum states in conventional electronics may beat end of Moore’s law

December 15th, 2019 at 12:12 pm » Comments Off

Graduate students Kevin Miao, Chris Anderson, and Alexandre Bourassa monitor quantum experiments at the Pritzker School of Molecular Engineering Scientists at the University of Chicago’s Pritzker School of Molecular Engineering have found a way to produce quantum states in ordinary, everyday electronics. By harnessing the properties of quantum mechanics without exotic materials or equipment, this […]



Volkswagen demonstrates first successful real-world use of quantum computing to help optimize traffic routing

December 14th, 2019 at 1:30 pm » Comments Off

A quantum computer from D-Wave. Copyright: D-Wave. Volkswagen AG has successfully demonstrated the world’s first live use of quantum computing to help optimize traffic routing. During the Web Summit conference in Lisbon, Portugal, nine public transit buses used a traffic management system developed by Volkswagen scientists in the United States and Germany, powered by a […]



Google says its quantum computer has just completed a 10,000-year task in less than four minutes

November 3rd, 2019 at 3:22 am » Comments Off

‘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

November 2nd, 2019 at 3:15 am » Comments Off

Google’s Sycamore chip powers a quantum computer  The era of practical quantum computers has begun — at least on one speed test showing “quantum supremacy.” A Google quantum computer has far outpaced ordinary computing technology, an achievement called quantum supremacy that’s an important milestone for a revolutionary way of processing data. Google disclosed the results […]



‘Quantum Apocalypse’: How ultra-powerful computers could cripple governments and effectively break the internet

October 12th, 2019 at 3:43 pm » Comments Off

  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 […]
