| 摘 要： | 本文利用控制双量子点分子与超导传输线共振器(STLR)的大失谐相互作用,实现任意两个量子点分子之间的耦合和控制操作,整个操作过程对STLR的衰减和热场均不敏感。基于这种耦合和控制操作,提出了量子点分子纠缠态的浓缩方案,该方案最大成功概率为50%。

| Abstract: | Coupling and controlling between arbitrary two double quantum dot molecules can be implemented using quantum dot molecular and superconducting transmission line resonator (STLR). In the large detuning region,the interaction is insensitive to both the STLR decay and thermal field. Finally,a scheme for entanglement concentration with successfully probability 50% is proposed. |
