What is Quantum Entanglement?
Quantum entanglement is a real and measurable feature of quantum mechanics where correlated quantum states are affected by measuring one particle, regardless of distance. Experiments have confirmed entanglement, which underpins technologies like quantum computing and quantum cryptography. Albert Einstein initially called it "spooky action at a distance" in 1935, but decades of experiments have proven it to be a verified feature of quantum mechanics. Entanglement occurs when particles interact, forming a single quantum system with correlated states. [...]
