TL;DR: This review begins by reviewing protocols of quantum key distribution based on discrete variable systems, and considers aspects of device independence, satellite challenges, and high rate protocols based on continuous variable systems.

TL;DR: Quantum cryptography is arguably the fastest growing area in quantum information science as mentioned in this paper, and many quantum key distribution protocols have been proposed, both theoretically and experimentally, over the last few decades.
Journal ArticleDOI
Quantum digital signatures without quantum memory.
TL;DR: This work presents a QDS scheme where no quantum memory is required, which also needs just linear optics, which makes QDSs feasible with current technology.
Journal ArticleDOI
Realization of quantum digital signatures without the requirement of quantum memory
Robert J. Collins,Ross J. Donaldson,Vedran Dunjko,Vedran Dunjko,Petros Wallden,Patrick J. Clarke,Erika Andersson,John Jeffers,Gerald S. Buller +8 more
TL;DR: This work presents the first realization of a scheme that does not need quantum memory and which also uses only standard linear optical components and photodetectors, and significantly advances quantum digital signatures as a quantum technology with potential for real applications.
Journal ArticleDOI
Quantum digital signatures with quantum-key-distribution components
Petros Wallden,Petros Wallden,Vedran Dunjko,Vedran Dunjko,Adrian Kent,Adrian Kent,Erika Andersson +6 more
TL;DR: This work presents two QDS protocols which have the same experimental requirements as quantum key distribution, which is already commercially available and gives a security proof for the presented QDS schemes against coherent forging attacks.
