Lower bound of concurrence based on D-type positive map

Lifang Niu, Zhoubo Duan

Published Aug 1, 2018• 0 citations

Abstract

In this paper, by using the D-type map, we provide an analytical lower bound of concurrence of arbitrary dimensional bipartite quantum system. It is shown that this lower bound is able to improve the existing bounds and detect entanglement better.

Lower Bound of Concurrence Based on Generalized Positive Maps

Huihui Qin, Shao-Ming Fei

We study the concurrence of arbitrary dimensional bipartite quantum systems. By using a positive but not completely positive map, we present an analytical lower bound of concurrence. Detailed examples are used to show that our bound can detect entanglement better and can improve the well known existing lower bounds.

Lower bound of concurrence based on positive maps

Xiaosheng Li, Xiu-Hong Gao, Shao-Ming Fei

We study the concurrence of arbitrary dimensional bipartite quantum systems. An explicit analytical lower bound of concurrence is obtained which detects entanglement for some quantum states better than some well-known separability criteria and improves the lower bounds, such as from the positive partial transposition, realignment criteria, and Breuer's entanglement witness.

A note on lower bounds of concurrence for arbitrary dimensional bipartite quantum states

Zhi-Bo Chen, Shao-Ming Fei

Abstract Quantification of quantum entanglement plays a crucial role in the study of quantum information tasks. We present analytical lower bounds for both concurrence and 2-concurrence based on the correlation matrices of bipartite quantum states. Compared with other related lower bounds, our approach provides a better estimation of the entanglement, particularly for states with large purity.

Lower bound of multipartite concurrence based on subquantum state decomposition

Xue‐Na Zhu, Ming‐Jing Zhao, Shao-Ming Fei

We study the entanglement of tripartite quantum states and provide analytical lower bounds of concurrence in terms of the concurrence of substates. The lower bound may improve all of the existing lower bounds of concurrence. The approach is generalized to arbitrary dimensional multipartite systems.

Lower bound on concurrence and distillation for arbitrary-dimensional bipartite quantum states

Ming‐Jing Zhao, Xue‐Na Zhu, Shao-Ming Fei +1 more

We present a lower bound of concurrence for arbitrary-dimensional bipartite quantum states. This lower bound may be used to improve all the known lower bounds of concurrence. Moreover, the lower bound gives rise to an operational sufficient criterion of distillability of quantum entanglement. The significance of our result is illustrated by quantitative evaluation of entanglement for entangled states that fail to be identified by the usual concurrence estimation method and by showing the distillability of mixed states that cannot be recognized by other distillability criteria.
