Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Over a decade ago, when I was first starting to pretend I could write about quantum mechanics, I covered a truly bizarre experiment. One half of a pair of entangled photons was sent through a device ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
