Abstract

Quantum key distribution (QKD) is a mature technology that establishes symmetric encryption keys between two remote parties in an unconditionally secure way. It has been successfully implemented in a variety of real-world scenarios, including cross-border networks, underwater links, and QMAN. In this paper, we present the latest results from our real-world implementations of QKD, demonstrating its adaptability and effectiveness in different environments.

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.

Secure communication and information protection become more and more important in the modern society. Quantum key distribution (QKD) enables two remote legitimate users to share unconditionally secure keys. Different from the former ones, the security of these keys is based on the principles of quantum physics and could be proved. Combined with one-time pad encryption, QKD can provide us an effective way for secure communication and information protection[1, 2]. Since Bennett and Brassard proposed the famous BB84 protocol[3], QKD or quantum cryptography has become one of the most dynamic research fields. After about twenty years of development, experimental QKD has achieved significant improvements, such as the transmission distance increased from 32 cm[4]to 260 km[5], the speed increased from 200 Hz[4]to 10 GHz[6].

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.

Quantum key distribution (QKD) is a technology that allows sharing secret cryptographic keys between two distant users (Alice and Bob), whose intrinsic security is guaranteed by fundamental principles of quantum mechanics. QKD is a mature technology: in Europe, all the 27 EU member states are working in a European Commission initiative (EuroQCI) to design, develop and deploy a quantum communication infrastructure composed by several national networks. For example, in Italy, the Italian Quantum Backbone will be used as a quantum communication testbed within the project QUID, that is in charge of the realization of the Italian part of EuroQCI.

Quantum Key Distribution

The convergence of quantum cryptography with applications used in everyday life is a topic drawing attention from the industrial and academic worlds. The development of quantum electronics has led to the practical achievement of quantum devices that are already available on the market and waiting for their first application on a broader scale. A major aspect of quantum cryptography is the methodology of Quantum Key Distribution (QKD), which is used to generate and distribute symmetric cryptographic keys between two geographically separate users using the principles of quantum physics. In previous years, several successful QKD networks have been created to test the implementation and interoperability of different practical solutions. This article surveys previously applied methods, showing techniques for deploying QKD networks and current challenges of QKD networking. Unlike studies focusing on optical channels and optical equipment, this survey focuses on the network aspect by considering network organization, routing and signaling protocols, simulation techniques, and a software-defined QKD networking approach.
