Helium—the lightest atom that can be laser-cooled and controlled—powers a new design for high-powered, stable quantum computers.Quantum Physics NewsRead More

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
