    "abstract": "The Peres-Horodecki criterion of positivity under partial transpose is\nstudied in the context of separability of bipartite continuous variable states.\nThe partial transpose operation admits, in the continuous case, a geometric\ninterpretation as mirror reflection in phase space. This recognition leads to\nuncertainty principles, stronger than the traditional ones, to be obeyed by all\nseparable states. For all bipartite Gaussian states, the Peres-Horodecki\ncriterion turns out to be necessary and sufficient condition for separability.",
