Quantum Entanglement

Quantum entanglement is the pinnacle of spooky physics—Einstein called it "spooky action at a distance" and refused to believe it was real. In 2022, Alain Aspect, John Clauser, and Anton Zeilinger won the Nobel Prize for proving it, with Aspect's experiments reducing loopholes to below 0.1%. When two particles are entangled, measuring one instantly determines the state of the other—regardless of distance. Chinese scientists demonstrated this across 1,200 kilometers using the Micius satellite in 2017, a distance 30% greater than the 920 km achieved in 2016. The implications for quantum computing, cryptography, and teleportation of information are staggering.
