Title: Detection of the maximally connected state

Abstract

The maximally connected state (MCS) which was first introduced by Briegel and Raussendorf [Phys. Rev. Lett. 86, 910 (2001)] has many interesting properties in quantum information theory. Many important states that we are focusing on currently are included in this special set of states. To decide whether a state is a MCS or not is the main problem concerned in this paper. In this paper (1) we give a general criterion for MCS; (2) when the ranks of all of the two-qubit reduced density matrices are two, we give a convenient criterion.
