绝热三能级系统的精确解和磁单极子

Exact solutions and magnetic monopoles in adiabatic three level systems

Timo Aukusti Laine

摘要:

研究了受激拉曼绝热通道中三能级系统中与薛定谔方程相关的几何相位。我们明确地解决了一个对偶模型,其中的脉冲施加在违反直觉和直觉的顺序。我们发现,当脉冲面积有限时,会产生一对带相反电荷的磁单极子,导致末态粒子数的振荡。相移的应用包括例如量子计算中的相位门、量子密码学中的相位操纵和量子干涉中的相位相互作用。

英文摘要:

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.
