Abstract

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 applications. A QKD network consists of two or more
QKD nodes interconnected by optical fiber or free space links.
The secret keys are negotiated between any pair of QKD nodes,
and then they can be delivered to multiple users in various areas
for ensuring long-term protection and forward secrecy. We
commence by introducing the QKD basics, followed by reviewing
the development of QKD networks and their implementation in
practice. Subsequently, we describe the general QKD network
architecture, its elements, as well as its interfaces and protocols.
Next, we provide an in-depth overview of the associated physical
layer and network layer solutions, followed by the standardization
efforts as well as the application scenarios associated with QKD
networks. Finally, we discuss the potential future research
directions and provide design guidelines for QKD networks.
