The detection power of real entanglement witnesses under local unitary equivalence
Yi Shen, Lin Chen, Zhihao Bian
The imaginary unit has recently been experimentally proven to be indispensable for quantum mechanics. We study the differences in detection power between real and complex entan…

A characterization of entangled two-qubit states via partial-transpose-moments
Lin Zhang, Ming-Jing Zhao, Lin Chen +2
Although quantum entanglement is an important resource, its characterization is quite challenging. The partial transposition is a common method to detect bipartite entanglement. In…
