Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...

Quantum entanglement is one of the strangest and most fascinating phenomena in physics. Even Einstein didn’t believe it - he called it “spooky action at a distance” - but science has proven it true.
