Numerical detection of Gaussian entanglement and its application to the identification of bound entangled Gaussian states
Shan Ma, Shibei Xue, Yu Guo +1
We present a numerical method for solving the separability problem of Gaussian quantum states in continuous-variable quantum systems. We show that the separability problem can be c…

Preparation of bipartite bound entangled Gaussian states in quantum optics
Shan Ma, Matthew J. Woolley, Xiaojun Jia +1
The positivity of the partial transpose is in general only a necessary condition for separability. There exist quantum states that are not separable, but nevertheless are positive…
