Quantum entanglement, “the spooky action at a distance”, is a peculiar feature of quantum theory. It plays a crucial role in the nonlocality feature of quantum mechanics. In quantum information processing, entanglement becomes an important resource for various tasks, such as teleportation, quantum computation, and cryptography. Intuitively, entanglement means a strong nonlocal correlation between distant parties, which essentially offers a secure key generation tool. Various Bell’s inequality test experiments have proved that the eavesdropping (as a local hidden variable) can be fundamentally ruled out. In this talk, I shall establish the link between the basic concept of entanglement and the security of quantum key distribution. |
