- Abstract
The detection of entanglement is one of the most important problem in quantum information theory. Many separability criteria for bipartite system are hard to understand and calculate, or apply to multipartite system. This paper proposed a separability criterion based on the coefficient matrix for an arbitrary multipartite state. It could tell whether a state is a separable state or entangled state according to the rank of coefficient matrix. It demonstrates that this method can find the specifically separable form of a multipartite state by some explicit examples. Finally the proposed separability criterion is easy to understand and calculate. [ABSTRACT FROM AUTHOR]
