摘要
提出了一种利用V-型三能级原子与双模腔场的共振相互作用制备多原子及多腔场纠缠W态的新方案,并用共生纠缠度研究了该模型中的纠缠演化和热纠缠现象.
A new scheme for the preparation of multi-atom and nulti-cavity entangled W state via resonant interaction of V-type three-level atoms and two-mode cavity-field is proposed. Also the time evolution and the thermal entanglement of this model will be studied by the concept of concurrence in this paper.
