Long-distance and secure quantum key distribution (QKD) over a free-space channel

Quantum key distribution (QKD) is a technique that enables secure communications between devices using a cryptographic protocol that is partly based on quantum mechanics. This communication method ultimately allows two parties to encrypt and decrypt messages they send to each other using a unique key that is unknown to other parties.
