论文摘要
可以在$λ$ -Type配置中使用三级系统，以通过使用非亚伯利亚非绝热几何阶段来构建一套通用的量子门。这种结构允许高速操作时间减少破坏的影响。但是，这可能伴随着旋转波近似（RWA）的有效性的分解，这是由于反向旋转项和脉冲长度之间的可比时间尺度，这极大地影响了动力学。在这里，我们研究了耗散效应与RWA有效性之间的权衡，从而获得了自动量子门运行的最佳状态。
A three-level system can be used in a $Λ$-type configuration in order to construct a universal set of quantum gates through the use of non-Abelian non-adiabatic geometrical phases. Such construction allows for high-speed operation times which diminish the effects of decoherence. This might be, however, accompanied by a breakdown of the validity of the rotating wave approximation (RWA) due to the comparable time scale between counter-rotating terms and the pulse length, which greatly affects the dynamics. Here, we investigate the trade-off between dissipative effects and the RWA validity, obtaining the optimal regime for the operation of the holonomic quantum gates.
