Lower bound on concurrence for arbitrary-dimensional tripartite quantum systems
arXiv:1603.04716 · doi:10.1007/s11128-016-1369-x
Abstract
In this paper, we study the concurrence of arbitrary dimensional tripartite quantum systems. An explicit operational lower bound of concurrence is obtained in terms of the concurrence of sub-states. A given example show that our lower bound may improve the well known existing lower bounds of concurrence. The significance of our result is to get a lower bound when we study the concurrence of arbitrary dimensional multipartite quantum systems.
