A family of separability criteria and lower bounds of concurrence
Xian Shi, Yashuai Sun
The problem on detecting the entanglement of a bipartite state is significant in quantum information theory. In this article, we apply the Ky Fan norm to the revised realignment ma…
A Genuine Multipartite Entanglement Measure Generated by the Parametrized Entanglement Measure
Xian Shi
In this paper, we investigate a genuine multipartite entanglement measure based on the geometric method. This measure arrives at the maximal value for the absolutely maximally enta…
Entanglement polygon inequalities for pure states in qudit systems
Xian Shi
Entanglement is one of the important resources in quantum tasks. Recently, Yang [arXiv:2205.08801] proposed an entanglement polygon inequalities (EPI) in terms of some e…
Quantifying the entanglement of quantum states under the geometry method
Xian Shi, Lin Chen, Yixuan Liang
Quantifying entanglement is an important issue in quantum information theory. Here we consider the entanglement measures through the trace norm in terms of two methods, the modifie…
