Manipulating information (read, write, store and retrieve) in a quantum system

Quantum information processing and communication (QIPC)is a developing interdisciplinary research field, which has the potentional to generate a radically new quantum information technology in the future. It is known already that a new technology for information processing and communication based on the laws of quantum physics will be capable of performing some tasks that cannot be achieved with conventional IT (which is based on classical physics). Examples are the factoring of large composite integers, a problem on which many current public-key cryptosystems are based, efficient simulation of quantum systems (which would greatly benefit many research areas) and guaranteed secure cryptographic key distribution. Although working quantum cryptosystems exist and some very simple examples of processing have been demonstrated, quantum information processing and communication (QIPC) systems are still very much in their infancy. Much research and development still needs to be done, to turn these into real technology for the future information society.

Results, presented at the QIPC workshop, held at Keble College Oxford on July 2003, included: the extension of working quantum cryptosystems to over 100km and the development of such systems based on

continuous light pulses, the distribution of quantum entanglement through free space across the river Danube, decoherence measurements on a single electronic spin and results showing the possibility of entanglement between atoms held in optical lattices. Projects currently funded: The full list of currently funded projects is available at: www.cordis.lu/ist/fet/qipc.htm Future initiative: The 3rd QIPC call for proposals will focus on basic research aimed at the realization of a fully functional multiple qubit system. The theoretical framework under which these multiple qubit system operate will constitute an integral part of the forthcoming call for proposals.
