论文摘要
我们研究了刺激的拉曼绝热通道（Stirap）中三级系统中与Schrödinger方程相关的几何相。我们明确求解了双重模型，其中脉冲在违反直觉和直观的顺序中应用。我们表明，当脉冲区域是有限的时，会产生一对带有相反电荷的磁性单极，从而导致人群在最终状态上的振荡。相移的应用包括，例如，量子计算中的相位门，量子加密中的相操作以及量子干扰中的相位相互作用。
We investigate the geometrical phase associated to the Schrödinger equation in a three level system in Stimulated Raman Adiabatic Passage (STIRAP). We solve explicitly a dual model, in which the pulses are applied in the counterintuitive and intuitive order. We show that when the pulse areas are finite, a pair of magnetic monopoles with opposite charges are created resulting the oscillations of the populations on the final states. The applications of the phase shift include, for example, phase gates in quantum computing, phase manipulation in quantum cryptography and phase interactions in quantum interference.
