摘要：

The entanglement dynamics of two-qubit systems in different quantum noises areinvestigatedbymeansofthe operator-sum representation method.We find that, except for the amplitude damping and phase damping quantum noise, the sudden death of entanglement is always observed in different two-qubit systems with generalized amplitude damping and depolarizing quantum noise.
