QUROPE Quantum Information Processing and Communication in Europe

This will be a session open to all members of the QIP research community. The Program includes both European and non-European speakers and representatives of the European Commission.

We introduce a scheme for efficiently describing pure states of strongly correlated fermions in higher dimensions using unitary circuits featuring a causal cone. A local way of computing local expectation values is presented. We formulate a dynamical reordering scheme, corresponding to time-adaptive Jordan-Wigner transformation, that avoids nonlocal string operators. Primitives of such a reordering scheme are highlighted. Fermionic unitary circuits can be contracted with the same complexity as in the spin case.

Q-Essence project will have its session during the FP6 and FP7 QIP Open Day + FP6 IP Cluster Review that takes place on 6-8 July at Wadham College, Oxford, UK. The registration for the event is now open.

Organised by some of the QuReP partners, this workshop will gather around 50 to 70 scientists from various countries working in the field of coherent and quantum optical processes in solids. It will also pay a tribute to the memories of two researchers, well-known in the community, who disappeared in an air crash last year. The conference is in the direct continuation of SMQIOAS 2008 in Bozeman, Montana and of a series of European workshops organized for several years on quantum information in rare earth doped crystals.

University of Paderborn (UPB), Germany, will become the new Q-Essence beneficiary. Prof. Christine Silberhorn, previously in MPL, was appointed as a full professor at the University of Paderborn where she will continue her research in the Applied Physics group within the Center of Optoelectronics and Photonics (CeOPP).

An international team of physicists (involving physicists C. Monroe and A. Acin from the AQUTE and Q-ESSENCE projects respectively) has created the first system that can produce verifiably random numbers. The technique relies on the inherent uncertainties in quantum mechanics and future versions could help cryptographers to encode information more securely than ever before.
