论文摘要
我们通过使用超纯净的刺激的拉曼绝热通道(Sastirap)在实验和理论上研究了基态和第二个激发态之间人口的转移。我们表明,转移对脉冲振幅的变化(缩放误差)的变化具有明显的弹性,因此,将超级绝热过程从绝热的过程中继承了某些鲁棒性特征。特别是,我们提供了一个新的高原,该高原出现在相反的脉冲强度的高价值中,这超出了Sastirap的通常框架。
We study experimentally and theoretically the transfer of population between the ground state and the second excited state in a transmon circuit by the use of superadiabatic stimulated Raman adiabatic passage (saSTIRAP). We show that the transfer is remarkably resilient against variations in the amplitudes of the pulses (scaling errors), thus demostrating that the superadiabatic process inherits certain robustness features from the adiabatic one. In particular, we put in evidence a new plateau that appears at high values of the counterdiabatic pulse strength, which goes beyond the usual framework of saSTIRAP.
