文摘We investigate the dynamics of entanglement for a two-parameter class of states in a hybrid qubit-qutrit system under the influence of various dissipative channels.Our results show that entanglement sudden death(ESD) is a general phenomenon and it usually takes place in a qubit-qutrit system interacting with various noisy channels,not only the case with dephasing and depolarizing channels observed by others.ESD can only be avoided for some initially entangled states under some particular noisy channels.Moreover,the environment affects the entanglement and the coherence of the system in very different ways.
