Quantum key distribution (QKD) is a secure communication method that implements a cryptographic protocol based on the laws of quantum mechanics, specifically quantum entanglement, the measurement-disturbance principle, and the no-cloning theorem. The goal of QKD is to enable two parties to produce a shared random secret key known only to them, which then can be used to encrypt and decrypt messages.
