多能级量子系统中选择性布居转移的解析脉冲设计:最大化布居振荡幅度

Analytic pulse design for selective population transfer in many-level quantum systems: maximizing amplitude of population oscillations

Duje Bonacci

摘要:

对原子、分子或量子点等离散能级量子系统的状态选择性制备和操纵是许多不同领域的最终工具,如化学反应的激光控制、原子光学、高精度计量学和量子计算。拉比振荡是实现这种操纵的最简单但可能非常有用的机制之一。拉比理论认为,在二能级系统中,共振驱动导致两个能级之间周期性的、完全的布居振荡。本文提出了一种在一般离散多能级量子系统中产生类拉比振荡的解析优化算法。

英文摘要:

State selective preparation and manipulation of discrete-level quantum systems such as atoms, molecules or quantum dots is a the ultimate tool for many diverse fields such as laser control of chemical reactions, atom optics, high-precision metrology and quantum computing. Rabi oscillations are one of the simplest, yet potentially quite useful mechanisms for achieving such manipulation. Rabi theory establishes that in the two-level systems resonant drive leads to the periodic and complete population oscillations between the two system levels. In this paper an analytic optimization algorithm for producing Rabi-like oscillations in the general discrete many-level quantum systems is presented.
