Quantum correlations in and beyond quantum entanglement in bipartite continuous variable systems [PDF]
, 2012 This thesis explores the role of non-classical correlations in bipartite continuous variable quantum systems, and the approach taken is three-fold. We show that given two initially entangled atomic ensembles, it is possible to probabilistically increase ...
