WebJun 14, 2024 · QKD is a key sharing mechanism implemented in quantum cryptography to generate a perfectly random key that is shared between two nodes (traditionally called Alice and Bob). It is based on the principles of quantum mechanics, that is, Heisenberg’s uncertainty principle and no-cloning principle, to guarantee secure key distribution.

Quantum key distribution (QKD) is a secure communication method that implements a cryptographic protocol involving components of quantum mechanics. It enables two parties to produce a shared random secret key known only to them, which then can be used to encrypt and decrypt messages. The process of quantum key distribution is not to be confused with quantum cryptography, as it is the best-known example of a quantum-cryptographic task.
