First quantum computers need smart software

The world is about to have its first quantum computers. The complexity and power of quantum hardware, such as ion traps and superconducting qubits, are scaling up. Investment is flooding in: from governments, through the billion-dollar European Quantum Technology Flagship Program, for example; from companies, including Google, IBM, Intel and Microsoft; and from venture-capital firms, which have funded start-ups. One such is ours, Rigetti Computing, which in June opened the first dedicated facility for making quantum integrated circuits: Fab-1 in Fremont, California. The vision is that commercial quantum- computing services will one day solve problems that used to be unimaginably...

Quantum computers are about to get real

Posted by K R on

Although the term “quantum computer” might suggest a miniature, sleek device, the latest incarnations are a far cry from anything available in the Apple Store. In a laboratory just 60 kilometers north of New York City, scientists are running a fledgling quantum computer through its paces — and the whole package looks like something that might be found in a dark corner of a basement. The cooling system that envelops the computer is about the size and shape of a household water heater.

Quantum computers ready to leap out of the lab in 2017

Quantum computing has long seemed like one of those technologies that are 20 years away, and always will be. But 2017 could be the year that the field sheds its research-only image. Computing giants Google and Microsoft recently hired a host of leading lights, and have set challenging goals for this year. Their ambition reflects a broader transition taking place at start-ups and academic research labs alike: to move from pure science towards engineering. “People are really building things,” says Christopher Monroe, a physicist at the University of Maryland in College Park who co-founded the start-up IonQ in 2015. “I’ve...

First Reprogrammable Quantum Computer Created

Scientists have created the first programmable and reprogrammable quantum computer, according to a new study. The technology could usher in a much-anticipated era of quantum computing, which researchers say could help scientists run complex simulations and produce rapid solutions to tricky calculations. Previous research suggested that quantum computers could simultaneously perform more calculations in one instant than there are atoms in the universe. Prior work also found that such capabilities would allow quantum computers to solve certain problems much faster than conventional computers can, for instance, breaking encryption that would take regular computers longer than the lifetime of the sun...

Google, NASA put big money on D-Wave's quantum computer

Google. NASA. Lockheed Martin. Los Alamos National Laboratory. Big names in the worlds of big brains and cutting-edge technology are investing millions of dollars in the quantum computing technology of the Burnaby, B.C.-based company D-Wave. They say they're starting to see promising results, despite criticism from some quantum physicists that the technology might never live up to its promise. Quantum computing is a new form of computing based on quantum mechanics, the strange physics that affects very, very small particles such as atoms. In theory, it has the potential to revolutionize artificial intelligence, space travel and other fields by solving...
