Objective
The "Long Distance Photonic Quantum Communication":
- QuComm project will scale secure quantum communication towards longer distances, realise novel applications, and identify and transfer "spin-off" applications to industry. The physical resource explored are entangled quantum states having no classical counterpart. Work will be pursued on novel sources for direct generation of entangled photon states in electrically pumped structures and on diode laser pumped non-linear optical crystals, and on detectors or multiphoton states. Basic quantum information building blocks, such as teleportation and entanglement swapping will be developed, and field demonstrations will be used to validate the technology, both at 700-800nm (free space and optical fibres) and at1300 and 1550nm (telecom fibres and systems. The consortium consists of both universities and industries with a broad physics and technology background.
OBJECTIVES
The QuComm project objectives are:
- To extend experimental quantum communication protocols, notably quantum teleportation, entanglement swapping and entanglement quantum cryptography, towards longer distances, in particular to explore the physical resource of entangled states of multiple photons lacking a counterpart in classical physics;
- To experimentally demonstrate quantum communication protocols for cryptographic applications in point-to-point and multiparty quantum cryptography, using entangled quantum states to achieve an increased level of security compared to faint-pulse quantum cryptography;
- To validate optical quantum communication technologies in an application context through various field tests of the developed concepts and technologies;
- To identify and transfer "spin off" results from quantum communication technologies to industries, or to industries-to-be, notably SMEs.
DESCRIPTION OF WORK
The work will be divided into six workpackages (WPs) each with a designated WP leader.
WP0 is the management WP, dealing also with dissemination and industrial take-up of results.
WP1 on sources, and WP2 on quantum state analysers, form the enabling building blocks for the subsequent work. Once the sources and analysers/detectors are available (in some cases very early in the project) they will be transferred to the later Workpackages:
WP3 on entanglement enhanced quantum cryptography focused on entangled states and multi-party quantum cryptography,
WP4 on teleporting entanglement, and
WP5 on multimode and multistate protocols.
These will use the optimised sources and analysers for the realisation of quantum communication protocols, both significantly improved versions of earlier demonstrations as well as entirely novel protocols. In WP 6, on field tests, the assembled work in earlier workpackages will be used to conduct trials outside the laboratory setting.
By having a separately delineated workpackage, it will be possible to assure the availability of test sites, provide coherence in the goals of the field trials, and provide joint experience for the realisation of the trials. The management of the consortium will be with a management committee of one person from each partner (in most cases the same person as the WP leader), and one person from the associated partner. The progress of work will be monitored through bi-monthly management reports assembled by the WP leader and sent to the coordinator. The consortium will meet every six months to highlight the scientific work, to discuss the progress and discuss modifications to the project. A small industrial advisory committee will monitor the progress of the project and advise and assist in the transfer of industrially relevant results. The project will disseminate the results through regular channels, through the industrial advisors, as well as through the organisation of joint meetings and work shops with other communities.
