“Today, we’re announcing research that shows — for the first time in history — that a quantum computer can successfully run a verifiable algorithm on hardware,” Google writes in a new blog post. The ...

A few years back, Google made waves when it claimed that some of its hardware had achieved quantum supremacy, performing operations that would be effectively impossible to simulate on a classical ...

For the past decade, quantum computing has struggled to balance promise and practicality. While the world’s most advanced systems remain engineering marvels, they’re bedeviled by the same flaw: the ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...
