In a newly discovered letter written by Albert Einstein, the renowned physicist suggested there could be a link between the migrations of birds and "unknown" physical processes.

Imaginary numbers have real meaning in the world of quantum mechanics, where they carry information about physical states.

A phenomenon called "proton tunneling" may explain some DNA mutations, the study authors suggest.

Physicists have shown how a particle might show its face in a corner of an experiment without needing its body anywhere in sight, like a grin without a cat.

"Jiuzhang" would be the most powerful quantum computer in the world, capable of performing some tasks 100 trillion times faster than the world's fastest supercomputers.

If the Higgs boson really is decaying into pairs of muons in the Large Hadron Collider, that's a big deal for particle physics.

Can we blame gravity for one of quantum physics' most brain-numbing paradoxes — Schrödinger's cat?

Physicists have found a new paradox in quantum mechanics that throws doubt on some common-sense ideas about physical reality.

A team of physicists has devised a simple way to measure the duration of a bizarre phenomenon called quantum tunneling.
