摘要: Quantum entanglement plays a fundamental and important role in quantum information theory. In this talk, we discuss the behavior of physical positive linear maps in fermionic systems, and then propose the phase partial transpose and the phase entanglement negativity. We prove that the phase entanglement negativity is an entanglement monotone. In addition, we also discuss   entanglement witness for bipartite fermionic states.
