To predict when we’ll have a truly useful quantum computer, we need to know precisely what one is. Columnist Karmela Padavic-Callaghan finds that’s harder to pin down than you might think ...

Three problems that are out of reach for conventional computers have been cracked by quantum computers and show how important ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would ...

The truth is less dramatic. There are three ways that AI and quantum computers overlap: first, in the problems they try to ...

The HAWK system isn't deployed anywhere, and Bitcoin doesn't use it. But is sitting in the same quantum race that Bitcoin ...

The only snag was that “Shor’s algorithm”, as it is now known, required something that at the time only existed on university ...

If you follow quantum computing news for long enough, it can start to seem like any quantum system that can alternate between ...

Sending quantum information through a chain of qubits, like energy through a Newton's cradle, could be the key to faster operations and take quantum computing to the next level.

Sabrina Gonzalez Pasterski built and flew an aircraft at the age of 14, graduated from MIT with a perfect GPA in three years, had her research cited by Stephen Hawking, and turned down offers from ...

Outdated computer networks across federal departments leave Australia's essential public services open to a rapidly accelerating wave of next-generation hacker threats.

On October 30, 1942, a group of destroyer warships from the British Royal Navy hunted down a Nazi submarine near the Nile Delta. The warships pounded the submarine with underwater explosions until it ...
