Which mechanism enables instantaneous key exchange in quantum cryptography?

💡 Explanation

Quantum entanglement allows two particles to be correlated regardless of distance; because measuring one entangled particle instantly determines the state of the other, quantum key distribution becomes possible; therefore 'entanglement', rather than other quantum effects, drives the key exchange.
