Quantum Key Distribution (QKD) networks have emerged the revolutionary technology in ensuring secure communication in the digital age. By utilizing the principles of quantum mechanics, QKD allows two parties to establish a secret key securely, which can subsequently be used for encrypting and decrypting sensitive information. While QKD holds immense promise for enhancing cybersecurity, it also presents several challenges that necessitate further research to achieve its full potential. The research presented here examines the development of QKD networks, their real-world use, as well as the general QKD network architecture and the most recent advancements in QKD network deployments.

Abstract Quantum key distribution (QKD) promises unconditional security in data communication and is currently being deployed in commercial applications. Nonetheless, before QKD can be widely adopted, it faces a number of important challenges such as secret key rate, distance, size, cost and practical security. Here, we survey those key challenges and the approaches that are currently being taken to address them.

Recent quantum key distribution deployments in UK and Europe from an industrial perspective

Mirko Pittaluga

Quantum Key Distribution (QKD) is a promising technology for securing future communications. Over the past thirty years, QKD developed from a theoretical idea to a mature technology that can provide Mbit/s key rates and that can be established over several hundred (up to a few thousand) of kilometres. One of the next challenges for this technology is proving its suitability for real-world operation scenarios. In this talk we will discuss recent QKD deployments executed in UK and Europe by Toshiba in collaboration with other partners, which demonstrate that the development of a stable, high performance, and widespread quantum communication network is in reach with current technology.

Towards Large Scale QKD networks.

Quantum Key Distribution technology is maturing quickly. The systems that were once closer to laboratory devices and focused on the single link are nowadays commercial products, and the companies that build them are ramping up production. Now there is a need to go beyond the single link and start thinking in getting closer to the network. In this talk we will explore, from a standardization point of view, the network architectures available and the gaps that need to be closed to support the creation of large-scale quantum secure networks, like the planned European Quantum Communications Infrastructure.

Architecture, security and topology of a global Quantum Key Distribution network

The performances of Quantum Key Distribution (QKD) systems have notably progressed since the early experimental demonstrations and several recent works indicate that the pace of this progression is very likely to be maintained -if not increased- in the future years. In parallel to this fast progression of QKD techniques, commercial products are also being developed, making QKD deployment for securization of some specific “real” data networks more and more likely to occur. It is the goal to the European project Secoqc to deploy a secure long-distance network based on quantum cryptography. It implies the conception of a specific architecture able to connect multiple users that may possibly be very far away from each other while QKD links are currently ″point-to-point only″and intrinsically limited in distance.
