When Non-Gaussian States are Gaussian: Generalization of Non-Separability Criterion for Continuous Variables
Derek McHugh, Vladimír Bužek, Mário Ziman
We present a class of non-Gaussian two-mode continuous variable states for which the separability criterion for Gaussian states can be employed to detect whether they are separable…

Entanglement, purity and energy: Two qubits vs Two modes
Derek McHugh, Mario Ziman, Vladimir Buzek
We study the relationship between the entanglement, mixedness and energy of two-qubit and two-mode Gaussian quantum states. We parametrize the set of allowed states of these two fu…
