Quantum Fisher information-based detection of genuine tripartite entanglement

Long-Mei Yang, Bao-Zhi Sun, Bin Chen, Shao-Ming Fei and Zhi-Xi Wang

Abstract

Genuine multipartite entanglement plays important roles in quantum information processing. The detection of genuine multipartite entanglement has been long time a challenging problem in the theory of quantum entanglement.

We propose a criterion for detecting genuine tripartite entanglement of arbitrary dimensional tripartite states based on quantum Fisher information. We show that this criterion is more effective for some states in detecting genuine tripartite entanglement by detailed examples.
