【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.更多还原

【Abstract】 Superadiabatic quantum control in the Rosen-Zener model is investigated. We introduce an additional field strength parameter,and discuss the influence of the additional field strength on the adiabatic process and the robustness of the technique to other field parameters.In addition,we define the instantaneous fidelity to test the adiabatic evolution of the system.The results show that,as long as the appropriate additional field is selected,the system can achieve adiabatic follow for all the time in the evolution process,and the whole evolution process is fast,high fidelity and with parameter robustness.更多还原
