Richard Feynman, one of the greatest physicists of the 20th century, once said something that should either comfort or terrify you: “Nobody understands quantum mechanics.” This wasn’t a confession of ...

SAN JOSE, Calif. -- Savvy enterprise leaders have had quantum computing in their sights, if not actively preparing for quantum technology and post-quantum cryptography. Soon, they might have to put ...

A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades. The findings could reshape ...

Future quantum computing will require correlations between distant modules—a feature known as distributed entanglement. Traditionally, such entanglement has relied on active control and repeated ...
