Coexistence of unlimited bipartite and multipartite Einstein-Podolsky-Rosen entanglement
Year: 2006
Type: preprint
Abstract: Quantum mechanics imposes 'monogamy' constraints on the sharing of entanglement. We show that, despite these limitations, entanglement can be simultaneously present in unlimited two-body and many-body forms in continuous variable systems. This is demonstrated in experimentally producible multimode states of light fields or atomic ensembles, which therefore enable infinitely more freedom in the distribution of information, as opposed to system of qubits where such entanglement structure is impossible. This is a central finding for the quantification, understanding and potential exploitation of shared quantum correlations, and may lead to novel realisations of robust multiparty communication networks and scalable quantum computation.
