A new entanglement measure: D-concurrence
ZhiHao Ma, Xiao-Dong Zhang
A new entanglement measure, which is called D-concurrence, is proposed. Then the upper and lower bounds for D-concurrence are obtained and the relationship between D-concurrence an…

Metrics Of Quantum States
Zhi-Hao Ma, Fu-Lin Zhang, Jing-Ling Chen
In this paper, we study metrics of quantum states. These metrics are natural generalization of trace metric and Bures metric. We will prove that the metrics are joint convex and co…
