This review article surveys the range of challenges (such as secret key rate, distance, size, cost and practical security) that need to be addressed to facilitate widespread commercial deployment of secure quantum key distribution technologies. The article describes the approaches being pursued to address these challenges and gives a very extensive list of technical references.
Quantum Key Distribution (QKD); Component characterization: characterizing optical components for QKD systems. ETSI GS QKD 011 V1.1.1
The latest ETSI standard document describes specifications and procedures for the characterization of optical components for use in QKD systems, including examples of specific tests and procedures for performing such tests
This paper highlights physical and application limitations with current QKD technologies. It thus highlights some of the key challenges being addressed by the QKD technology community today.
Avascent White Paper – E. Rolfe, Place Your Bets: Creating a quantum technology strategy for defense (sic) firms.
This paper is from a US consultancy firm, giving their take on how quantum computing, communications and cascade lasers could affect the strategy of companies serving the defence and intelligence sectors.
ETSI White Paper no 8 – Quantum Safe Cryptography and Security; An introduction, benefits, enablers and challenges
ISBN No. 979-10-92620-03-0. This is a very extensive paper which explains what “Quantum Safe” means, its applications and benefits, along with surveying the current state of the art in technologies (not just quantum) and protocols.
