*Quantum key exchange* (QKD for short) is a process in which two parties generate a [[Encryption Key|shared secret key]] using the laws of [[quantum mechanics]]. One algorithm to achieve this is [[BB84]].
Typically, eavesdropping by third parties can also be detected.
The generated key is used to transmit data securely using [[Symmetric Encryption|classical encryption methods]].
