论文摘要
为了一致控制几个量子的发射极,利用了狂犬病机制,通常使用具有能量共振的能量共振的脉冲,而单个异抗脉冲不会导致种群反转。令人惊讶的是,利用量子发射器种群(超级)机制的摇摆的两种彩色激发,结合了两种非谐振脉冲,能够反转系统。在本文中,我们对着装状态图片中的超级方案提供了深入的分析。我们表明,超级机制可以理解为穿着状态之间过渡的驱动。在两级系统中,这使我们能够得出产生种群反转的脉冲参数的分析表达式。我们将考虑因素扩展到三级系统,在该系统中,裸露状态之间发生了强烈的混合。从这些结果中获得的见解有助于寻找可访问的制度,以进一步实现超级方案和类似的两色兴奋方案。
To coherently control a few-level quantum emitter, typically pulses with an energy resonant to the transition energy are applied making use of the Rabi mechanism, while a single off-resonant pulse does not result in a population inversion. Surprisingly, a two-color excitation with a combination of two off-resonant pulses making use of the Swing-UP of quantum EmitteR population (SUPER) mechanism is able to invert the system. In this paper, we provide an in-depth analysis of the SUPER scheme within the dressed-state picture. We show that the SUPER mechanism can be understood as a driving of the transition between the dressed states. In the two-level system this allows us to derive analytic expressions for the pulse parameters yielding a population inversion. We extend our considerations to the three-level system, where a strong mixing between the bare states takes place. The insights gained from these results help in finding accessible regimes for further experimental realizations of the SUPER scheme and similar two-color excitation schemes.
