Quantum Cryptography Beyond Quantum Key Distribution [PDF]
Designs, Codes and Cryptography, 2015 Quantum cryptography is the art and science of exploiting quantum mechanical effects in order to perform cryptographic tasks. While the most well-known example of this discipline is quantum key distribution (QKD), there exist many other applications such

The case for quantum key distribution [PDF]
, 2009 Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures.

Security of Quantum Key Distribution
IEEE Access, 2016 The security issues facing quantum key distribution (QKD) are explained, herein focusing on those issues that are cryptographic and information theoretic in nature and not those based on physics. The problem of security criteria is addressed.

Chip-based quantum key distribution [PDF]
Nature Communications, 2017 Quantum key distribution has not been widely adopted in part due to technical hurdles preventing it being fully integrated in classical communication networks.

Noiseless Linear Amplifiers in Entanglement-Based Continuous-Variable Quantum Key Distribution
Entropy, 2015 We propose a method to improve the performance of two entanglement-based continuous-variable quantum key distribution protocols using noiseless linear amplifiers. The two entanglement-based schemes consist of an entanglement distribution protocol with an

A Key Verification Protocol for Quantum Key Distribution [PDF]
IEEE Access, 2019 Sharing a secret key between two physically separated nodes, Alice and Bob, is possible through the use of quantum key distribution (QKD) techniques.

Numerical finite-key analysis of quantum key distribution
npj Quantum Information, 2020 Quantum key distribution (QKD) allows for secure communications safe against attacks by quantum computers. QKD protocols are performed by sending a sizeable, but finite, number of quantum signals between the distant parties involved. Many QKD experiments,

Quantum Key Distribution [PDF]
ACM Computing Surveys, 2020 The convergence of quantum cryptography with applications used in everyday life is a topic drawing attention from the industrial and academic worlds. The development of quantum electronics has led to the practical achievement of quantum devices that are already available on the market and waiting for their first application on a broader scale.

No Signaling and Quantum Key Distribution [PDF]
Physical Review Letters, 2005 Standard quantum key distribution protocols are provably secure against eavesdropping attacks, if quantum theory is correct. It is theoretically interesting to know if we need to assume the validity of quantum theory to prove the security of quantum key distribution, or whether its security can be based on other physical principles.
