IEE Seminar on Quantum Cryptography: Secure Communications, 2005
This paper presents a slide presentation of quantum key distribution (QKD) on existing networks. The limitations of QKD in existing network infrastructure and the proposed solutions are presented. The QKD in OSI model and an overview of different deployment scenarios are included in the presentation. (2 pages)

FBG-Based Multidimensional QKD
2018 20th International Conference on Transparent Optical Networks (ICTON), 2018In this paper, we propose several FBG-based both weak coherent state and entanglement assisted multidimensional QKD (MQKD) protocols with mutually unbiased bases (MUBs) derived from the complex Hadamard matrices. We also propose how to implement them by using FBGs with orthogonal impulse responses.

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 ...

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 ...

Quantum-Key Distribution (QKD) Fundamentals
2019This chapter is devoted to QKD fundamentals. The chapter starts with description of key differences between conventional cryptography, classical physical-layer security (PLS), and QKD. In section on QKD basics, after historical overview, we review different QKD types and describe briefly common postprocessing steps, namely, information reconciliation ...

SPIE Proceedings, 2006
Following a review of the measure of Renyi information gain and its optimization, the quantum circuits and designs are reviewed of optimized entangling probes for attacking the BB84 protocol of quantum key distribution (QKD), extracting maximum Renyi information on the pre-privacy amplified key.
