The Evolution of Quantum Key Distribution Networks: On the Road to the Qinternet

IEEE Communications Surveys and Tutorials, 2022
Quantum key distribution (QKD) constitutes a symmetric secret key negotiation protocol capable of maintaining information-theoretic security. Given the recent advances in QKD networks, they have evolved from academic research to some preliminary ...

Quantum key distribution

2021
Quantum key distribution (QKD) provides a means of secure communication between two parties. QKD exploits the principle that you cannot eavesdrop on a quantum communication channel without producing a detectable disturbance.

Experimental quantum key distribution certified by Bell's theorem

Nature, 2021
Cryptographic key exchange protocols traditionally rely on computational conjectures such as the hardness of prime factorization1 to provide security against eavesdropping attacks.

Overcoming the rate–distance limit of quantum key distribution without quantum repeaters

Nature, 2018
Quantum key distribution (QKD)1,2 allows two distant parties to share encryption keys with security based on physical laws. Experimentally, QKD has been implemented via optical means, achieving key rates of 1.26 megabits per second over 50 kilometres of ...

An Introduction to Practical Quantum Key Distribution

IEEE Aerospace and Electronic Systems Magazine, 2021
Quantum technology, and especially quantum computing, is advancing rapidly. Our every-day secure communication infrastructure relies heavily on public key cryptography; unfortunately, many public key schemes are in fact insecure against quantum ...

Quantum key agreement

Proceedings. 1998 IEEE International Symposium on Information Theory (Cat. No.98CH36252), 2002
We consider quantum key agreement between two users Alice and Bob in which an eavesdropper Eve intercepts and resends photons. We show how Alice and Bob attain a probabilistic upper bound on Eve's knowledge.

Quantum Computing: Quantum Key Distribution

IOSR Journal of Computer Engineering, 2014
For the last fifty years computers have grown faster, smaller, and more powerful transforming and benefiting our society in ways too numerous to count. But like any exponential explosion of resources, this growth — known as Moore's law — must soon come to an end. Research has already begun on what comes after our current computing revolution.
