Separability criteria for continuous variable systems
Kazuo Fujikawa
A general separability condition on the second moment (covariance matrix) for continuous variable two-party systems is derived by an analysis analogous to the derivation of the Ken…

Analytic solution of the separability criterion for continuous variable systems
Kazuo Fujikawa
By using the algebraic separability criterion of R. Simon, we present an explicit determination of squeezing parameters for which the P-representation condition saturates the $Sp(2…
