Towards probabilistic entanglement of distant atoms — •Markus Hennrich, Felix Rohde, Carsten Schuck, and Jürgen Eschner — ICFO - Institut de Ciències Fotòniques, Jordi Girona 29, Nexus II, 08034 - Barcelona, Spain

Non-local entanglement is considered a key resource in future quantum information processing. One of its applications is the implementation of quantum communication schemes over long distances [1]. Such non-local entanglement has been realized e.g. between two photons [2] and between an atom and a photon [3]. A proximate step towards distributed quantum information processing is the generation of entanglement of distant massive particles like single atoms, as e.g. proposed by Cabrillo et al. [4]. This scheme relies on the projective measurement of photons scattered from two distant atoms after excitation by a common laser pulse. Here we describe our plans for an experimental realization of this scheme.
