For decades, physicists have worked to prove the strange predictions of quantum mechanics with real experiments. As quantum computers have grown more powerful, researchers have devised increasingly sophisticated ways to test whether these machines are truly harnessing quantum effects—but every method so far has run into limits.Quantum Physics NewsRead More

Superfluid helium could offer a new way to tackle one of the biggest challenges in scaling up quantum computers, say researchers from the University of Surrey. The research team has introduced a conceptual design for a new type of qubit that could be much less vulnerable to errors.Quantum Physics NewsRead More
