What is Quantum Cryptography?
Quantum cryptography, also known as quantum key distribution (QKD), relies on the unique properties of quantum mechanics to create secure keys for encryption. When two parties want to communicate securely, they use QKD to encode a random key onto a quantum particle, such as a photon. This key is then measured by the receiver, and the information is transmitted in a way that makes it impossible for anyone to intercept and decode without being detected.
