Positive finite rank elementary operators and characterizing entanglement of states
Xiaofei Qi, Jinchuan Hou
In this paper, a class of indecomposable positive finite rank elementary operators of order are constructed. This allows us to give a simple necessary and sufficient criter…

Continuous variable entanglement enhancement and manipulation by a sub-threshold type-II optical parametric amplifier
Yana Shang, Xiaojun Jia, Yumei Shen +2
We experimentally demonstrate that the quantum entanglement between amplitude and phase quadratures of optical modes produced from a non-degenerate optical parametric amplifier (NO…
