quantum entanglement
Quick Summary
Quantum entanglement is a phenomenon where subatomic particles become linked, sharing a common quantum state. This means a characteristic of one particle, like its spin, is directly correlated with the same characteristic of another particle, regardless of the distance separating them.1
This interconnectedness was famously analyzed by Einstein, Podolsky, and Rosen (EPR) in 1935. They argued that if quantum mechanics' predictions were correct, it implied an incomplete description of reality, suggesting a "spooky action at a distance". Experiments, however, have largely supported quantum mechanics, indicating that these correlated particles do influence each other instantaneously, even across vast distances, challenging classical notions of locality. Physicists like Charles H. Bennett have explored applications of entanglement in fields such as quantum cryptography and teleportation.234

Gilles Brassard…particle to another by using quantum entanglement. Two particles can be in a single entangled state such that measuring a property of one particle instantly determines that same property in another particle. For example, two particles are in a state in which one is spin-up and the other is spin-down.…
