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…
Entanglement criterion based on skew information
Zhihao Ma
we can establish an entanglement criteria from skew information. our criterion is independent of Local Uncertainty Relations.
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…
Super fidelity and related metric
Zhi-Hao Ma, Fu-Lin Zhang, Zhi-Hua Chen +1
We report a new metric of quantum states. This metric is build up from super-fidelity, which has deep connection with the Uhlmann-Jozsa fidelity and plays an important role in quan…
Geometric interpretation for A-fidelity and its relation with Bures fidelity
Zhihao Ma, Fu-Lin Zhang, Jing-Ling Chen
A geometric interpretation for the A-fidelity between two states of a qubit system is presented, which leads to an upper bound of the Bures fidelity. The metrics defined based on t…
Matrix realignment and partial transpose approach to entangling power of quantum evolutions
Zhihao Ma, Xiaoguang Wang
Based on the matrix realignment and partial transpose, we develop an approach to entangling power and operator entanglement of quantum unitary operators. We demonstrate efficiency…
