【摘要】：研究了Rosen-Zener模型的超绝热量子调控问题.通过引入了一个附加场强度参数,讨论了附加场大小对绝热过程的影响.同时分析了该方法对其它外场参数的鲁棒性.另外,定义了瞬时保真度,检验了这种方法的有效性.结果表明,只要选择合适的附加场,系统在演化过程中的每一时刻,都能实现绝热跟随,整个演化过程具有快速性、高保真度和参数鲁棒性.
[Abstract]:In this paper, the problem of superadiabatic caloric control in Rosen-Zener model is studied. The influence of the size of the additional field on the adiabatic process is discussed by introducing an additional field strength parameter. At the same time, the robustness of the method to other external field parameters is analyzed. In addition, the instantaneous fidelity is defined and the validity of this method is tested. The results show that the adiabatic follow can be achieved at every moment in the evolution process as long as the appropriate additional field is selected. The whole evolution process is characterized by rapidity, high fidelity and parameter robustness.
