Robust tripartite-to-bipartite entanglement localization by weak measurements and reversal
Chunmei Yao, Zhi-Hao Ma, Zhi-Hua Chen +1
We propose a robust and efficient approach for tripartite-to-bipartite entanglement localization. By using weak measurements and quantum measurement reversal, an almost maximal ent…
Multipartite Quantum Correlations in Open Quantum Systems
Zhi-Hao Ma, Zhi-Hua Chen, Felipe F. Fanchini
In this paper we present a measure of quantum correlation for a multipartite system, defined as the sum of the correlations for all possible partitions. Our measure can be defined…
Estimating entanglement monotones with a generalization of the Wootters formula
Zhi-Hua Chen, Zhi-Hao Ma, Otfried Gühne +1
Entanglement monotones, such as the concurrence, are useful tools to characterize quantum correlations in various physical systems. The computation of the concurrence involves, how…
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…
