Advances in Quantum Cryptography

Understand

Quantum cryptography is arguably the fastest growing area in quantum information science.

• Novel theoretical protocols are designed on a regular basis, security proofs are constantly improving, and experiments are gradually moving from proof-of-principle lab demonstrations to in-field implementations and technological prototypes.
• In this review, we provide both a general introduction and a state of the art description of the recent advances in the field, both theoretically and experimentally.
• We start by reviewing protocols of quantum key distribution based on discrete variable systems.
