Improved lower bounds on genuine-multipartite-entanglement concurrence
Zhi-Hua Chen, Zhi-Hao Ma, Jing-Ling Chen +1
Genuine-multipartite-entanglement (GME) concurrence is a measure of genuine multipartite entanglement that generalizes the well-known notion of concurrence. We define an observable…
Detecting the concurrence of an unknown state with a single observable
Zhi-Hao Ma, Zhi-Hua Chen, Jing-Ling Chen
While the detection of entanglement has been proved already to be quite a difficult task, experimental quantification of entanglement is even more challenging. In this work, we der…
Witness to detect quantum correlation of bipartite states in arbitrary dimension
Zhi-Hao Ma, Zhi-Hua Chen, Jing-Ling Chen
In this work we introduce a nonlinear witness that is a sufficient condition for detecting the vanishment of quantum correlation of bipartite states. Our result directly generalize…
Criteria For -Separability Of Multipartite Quantum State
Zhi-Hao Ma, Zhi-Hua Chen, Jing-Ling Chen
We derive criteria for -separability of multipartite Quantum state
Measure of genuine multipartite entanglement with computable lower bounds
Zhi-Hao Ma, Zhi-Hua Chen, Jing-Ling Chen +3
We introduce an intuitive measure of genuine multipartite entanglement which is based on the well-known concurrence. We show how lower bounds on this measure can be derived that al…
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…
