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

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

We think of it as rigid, smooth, and unidirectional – the arrow of time flies straight and true, and all we can do is go ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades ...

For the first time, physicists have entangled two atoms while they were in motion and used the result to run one of quantum ...

Google's latest Doodle highlights quantum physics, showcasing the Bloch sphere and qubits. This celebrates World Quantum Day, ...
