The Future of Quantum-Secure Communication: Quantum Cryptography Protocols

Chapter 1: Understanding Quantum Cryptography

Quantum cryptography secures communication channels by leveraging quantum mechanics concepts. Unlike classical cryptographic systems, which rely on mathematical complexity, quantum cryptography is based on physical rules, namely the behaviour of quantum objects such as photons. Quantum key distribution (QKD) is a fundamental idea in quantum cryptography that allows parties to share encryption keys securely by leveraging quantum entanglement and uncertainty principles.

Chapter 2: Quantum Key Distribution Protocols

Several quantum key distribution algorithms have been developed to create secure communication channels. Among the most prominent is the BB84 protocol, proposed by Charles Bennett and Gilles Brassard in 1984. BB84 uses photon polarisation to transfer cryptographic keys, ensuring security using quantum uncertainty concepts. Other protocols, including E91 and BBM92, improve key distribution efficiency and security.
