Peres-Horodecki Separability Criterion for Continuous Variable Systems

Peres-Horodecki Separability Criterion for Continuous Variable Systems

The Peres-Horodecki criterion of positivity under partial transpose is studied in the context of separability of bipartite continuous variable states. The partial transpose operation admits, in the continuous case, a geometric interpretation as mirror reflection in phase space. This recognition leads to uncertainty principles, stronger than the traditional ones, to …
