Abstract: (OSA Publishing)
Quantum cryptography is arguably the fastest growing area in quantuminformation science. Novel theoretical protocols are designed on a regularbasis, security proofs are constantly improving, and experiments aregradually moving from proof-of-principle lab demonstrations to in-fieldimplementations and technological prototypes. In this paper, we provideboth a general introduction and a state-of-the-art description of therecent advances in the field, both theoretical and experimental. We startby reviewing protocols of quantum key distribution based on discretevariable systems. Next we consider aspects of device independence,satellite challenges, and protocols based on continuous-variable systems.We will then discuss the ultimate limits of point-to-point privatecommunications and how quantum repeaters and networks may overcome theserestrictions. Finally, we will discuss some aspects of quantumcryptography beyond standard quantum key distribution, including quantumrandom number generators and quantum digital signatures.Note:
