New recipe for single-atom transistors may enable quantum computers with unparalleled memory and processing power

May 29th, 2020 at 9:11 am » Comments Off

  Single-Atom Transistor  Linking multiple copies of these devices may lay the foundation for quantum computing. Once unimaginable, transistors consisting only of several-atom clusters or even single atoms promise to become the building blocks of a new generation of computers with unparalleled memory and processing power. But to realize the full potential of these tiny […]



Wiring the quantum computer of the future: A novel simple build with existing technology

May 9th, 2020 at 2:30 pm » Comments Off

Efficient quantum computing is expected to enable advancements that are impossible with classical computers. Scientists from Japan and Sydney have collaborated and proposed a novel two-dimensional design that can be constructed using existing integrated circuit technology. This design solves typical problems facing the current three-dimensional packaging for scaled-up quantum computers, bringing the future one step […]



Hot qubits break one of the biggest constraints to practical quantum computers

May 2nd, 2020 at 12:49 pm » Comments Off

Most quantum computers being developed around the world will only work at fractions of a degree above absolute zero. That requires multi-million-dollar refrigeration and as soon as you plug them into conventional electronic circuits they’ll instantly overheat. But now researchers led by Professor Andrew Dzurak at UNSW Sydney have addressed this problem. “Our new results […]



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

March 11th, 2020 at 11:24 am » Comments Off

“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, […]



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 […]
