Information reconciliation for QKD
Quantum Information and Computation, 2011Quantum key distribution (QKD) relies on quantum and classical procedures in order to achieve the growing of a secret random string ---the key--- known only to the two parties executing the protocol. Limited intrinsic efficiency of the protocol, imperfect devices and eavesdropping produce errors and information leakage from which the set of measured ...

QKD and frequency distribution cooperation: the Twin-field QKD case
2022 IEEE 15th Workshop on Low Temperature Electronics (WOLTE), 2022The integration of Quantum Key Distribution (QKD) protocols in metropolitan networks, exploiting already deployed telecommunication fibers, requires particular attention due to the non-ideal environment in which the protocol operates. At present, Twin-field QKD is one of the most promising techniques to reach the extension of QKD transmission but its ...

Deployed QKD Networks in Europe
2023 Optical Fiber Communications Conference and Exhibition (OFC), 2023We report several use-case demonstrations for quantum key distribution in deployed fiber networks. The tests were carried out under real world conditions at the end-user premises using commercial QKD systems.

Joint QKD-Post-Quantum Cryptosystems
IEEE Access, 2020 To extend the transmission distance and/or improve secret-key rate of QKD protocols, we propose to employ the joint QKD-post-quantum cryptosystems in which QKD is used for raw-key transmission while the post-quantum cryptography (PQC) subsystem to ...

Chapter 12 provided a basic overview of the hardware components in a quantum key distribution (QKD) system. We also explored the Tokyo QKD Network built to test the threat resilience of QKD. In this chapter we'll delve into larger implementations of this technology, exploring the basics of a total of five major QKD networks.

Quantifying the security of a QKD protocol
2015 IEEE International Conference on Advanced Networks and Telecommuncations Systems (ANTS), 2015In this paper we develop the concept of quantifying the security of a quantum cryptographic scheme. We focus on BB84 and develop a model for measuring the security offered by protocols that follow a similar model. We also present a new model for entropy of detection assuming a binomial probability distribution.

Device-Independent Quantum Key Distribution (DIQKD) deals with the problem that security proofs often only apply to the ideal setting of the theoretical protocol and do not take into account the problems that arise when implementing a protocol, such as the photon-number-splitting attack.

AIP Conference Proceedings, 2012
The present document starts with a brief introduction of ETSI, followed by an overview of locations where QKD has already been deployed commercially. The various scenarios of QKD deployment lead to a strong need for standardization. Before going into detail about the work of the ETSI standardization group for QKD the paper gives some general ...
