entangled particles
Spookily correlated quanta
Entangled particles are particles whose quantum states remain correlated regardless of the distance between them.
Measuring one particle instantly affects what can be known about its partner—if one has spin up, the other has spin down.
Einstein famously called this "spooky action at a distance," doubting its reality, but experiments have confirmed entanglement occurs.
The phenomenon underlies quantum computing and quantum cryptography.
