Einstein called it “spooky action at a distance,” but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become ...

One hundred years after its birth, quantum mechanics remains one of the most powerful and successful theories in all of ...

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

The theory of quantum mechanics has transformed daily life since being proposed a century ago, yet how it works remains a mystery—and physicists are deeply divided about what is actually going ...

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, connects quantum ...

"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics. Paradoxically, his theory of relativity has become an essential tool for ...

In commemoration of the 100th anniversary of modern quantum mechanics, a survey asked physicists for their takes on some hot questions in quantum theory.

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of physics.
