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…
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…
