quantum cryptography

n.
Any of various techniques that exploit quantum-mechanical phenomena, such as superposition or quantum entanglement, to generate and share between two parties a private key that can be used to encrypt and decrypt data. Current techniques also reveal any attempt to intercept the private key during its creation.

quantum cryptography

n
(Atomic Physics) a method of coding information based on quantum mechanics, which is said to be unbreakable
