QUROPE Quantum Information Processing and Communication in Europe

The first report of the "Russian Quantum Center" (RQC, http://www.rqc.ru) has been made public recently. It presents the results of research work since 2012, when the organizational period ended and the RQC began full operation. You can grab a copy here.

A participatory workshop on Quantum Technologies and Industry was held in Brussels on 6 May 2015. The aim was to identify what could be the markets for quantum technologies, and how these could be industrialised. The workshop report (available here) summarises the discussions and the action plan which emerged as a conclusion.

Displaced single-photon entanglement is a simple form of optical entanglement, obtained by sending a photon on a beam splitter and subsequently applying a displacement operation. We show that it can generate, through a momentum transfer in the pulsed regime, an optomechanical entangled state involving macroscopically distinct mechanical components, even if the optomechanical system operates in the singlephoton weak coupling regime. We discuss the experimental feasibility of this approach and show that it might open up a way for testing unconventional decoherence models
