    Separability Criterion for Gaussian States

    The PPT (positivity under partial transpose) criterion is studied in the context of separability of continuous variable bipartite states. The partial transpose operation admits, in the Wigner representation of...

    Geometric Representation for Squeezing: The abcd-Law

    Squeezed coherent states (Gaussian pure states) are fully characterized by the first and second moments of the canonical operators1,2. This leads to convenient representations for the unitary evolution of these s...

    Geometric Phases in Optics: Some Pedestrian Considerations

    Optical experiments have played an important role in verifying various predictions related to geometric phases1–6. It is in optics that Berry’s original ideas were first experimentally confirmed2. Again it is in ...
