SECOQC - Development of a Global Network for Secure Communication based on Quantum Cryptography

This is the home page of the Integrated Project SECOQC, Sixth Framework Programme, of the European Union.

The first live demonstration of a working quantum key distribution (QKD) network will take place in Vienna in the framework of the SECOQC Demonstration and International Conference. Seven QKD-links will be combined in a novel quantum-back-bone network physically deployed within a typical metropolitan area network to connect different company sites from SIEMENS Austria. Typical applications for QKD, to secure data traffic from telephony and video conferencing, will also be included in the demonstration.

Also included in the conference program is the kick-off of the ETSI Industry Specification Group on Quantum Cryptography and Quantum Technologies - an output of the SECOQC standardisation initiative. (to standards page ››)

Publication of Quantum Backbone Link Interface

The participants of the European Integrated Project SECOQC of the 6^th framework programme, represented by the co-ordinator Austrian Research Centers GmbH - ARC, are proud to announce the publication of the Quantum-Back-Bone Link-Interface QBB-LI. By this interface quantum cryptographic links can be inserted into the SECOQC Quantum Back Bone secrets distribution network.

Published is the complete interface documentation, as well as a software package including a network node simulator and a sample quantum device.

Outline of the SECOQC Quantum-Key-Distribution Network in Vienna

Andreas Poppe, Momtchil Peev, Oliver Maurhart

Abstract: A Quantum Key Distribution (QKD) network is currently implemented in Vienna by integrating seven QKD-Link devices that connect five subsidiaries of SIEMENS Austria. We give an architectural overview of the network and present the enabling QKD-technologies, as well as the novel QKD network protocols.

SECOQC White Paper on Quantum Key Distribution and Cryptography

The White Paper is the outcome on a thorough consultation and discussion among the participants of the European project SECOQC. This paper is a review article that attempts to position Quantum Key Distribution (QKD) in terms of cryptographic applications. A detailed comparison of QKD with the solutions currently in use to solve the key distribution problem, based on classical cryptography, is provided. We also detail how the work on QKD networks lead within SECOQC will allow the deployment of long-distance secure communication infrastructures based on quantum cryptography. The purpose of the White Paper is finally to promote closer collaboration between classical and quantum cryptographers. We believe that very fruitful research, involving both communities, could emerge in the future years and try to sketch what may be the next challenges in this direction.
