The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, ...

After 30 months of fast-paced innovation in quantum algorithms, six research groups are hoping to hit paydirt. But there can be only one big winner—if there is a winner at all.

It's when research becomes ongoing rather than episodic that innovation shifts from isolated breakthroughs to durable, repeatable advantage.

Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic method for quantum computers. It makes errors in individual quantum bits ...

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems. Imagine a ...
