An important milestone for quantum computers seems to have been reached with Google using a quantum computer to solve a problem 1 billion times faster than the fastest supercomputer in the world. This ...

A new Swinburne study is addressing a core paradox: if quantum computing is solving problems that cannot be checked by conventional methods, how can we be certain the results are correct? Quantum ...

Peter Bierhorst’s machine is no pinnacle of design. Nestled in the Rocky Mountains inside a facility for the National Institute of Standards and Technology, the photon-generating behemoth spans an ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

Quantum computing is moving from lab curiosity to practical tool far faster than most people realize, and the shift could ...

Scientists from quantum computing company D-Wave have demonstrated that, using a method called quantum annealing, they could simulate some materials up to three million times faster than it would take ...

One of the secrets to building the world’s most powerful computer is probably perched by your bathroom sink. At IBM’s Thomas J. Watson Research Center in New York State’s Westchester County, ...

No, quantum computing did not come of age with Google’s Sycamore, a 53-qubit computer solving in 200 seconds a problem that would take even a supercomputer 10,000 years. Instead, it is the first step, ...

Quantum computing has great promise to solve problems that are too hard for classical computers to solve in reasonable amounts of time, but they are not yet practical There’s no lack of hype in the ...

Scientists and researchers have long extolled the extraordinary potential capabilities of universal quantum computers, like simulating physical and natural processes or breaking cryptographic codes in ...
