切脉冲驱动量子模型中的非绝热布居转移

Nonadiabatic population transfer in a tangent-pulse driven quantum model

Guang Yang, Wei Li, Li-Xiang Cen

摘要:

对量子系统动力学的精细控制是实现原子和分子系统量子信息处理和相干操纵的关键。在本文中,我们提出了一个控制协议,使用切线脉冲驱动模型,并证明它表明一个理想的设计,即,既快速又准确地转移人口。相对于现有的其他策略,本方案的一个显着特点是非绝热演化本身的高速度不仅不会导致不必要的过渡,而且还可以抑制由驱动脉冲截断引起的误差。

英文摘要:

Fine control of the dynamics of a quantum system is the key element to perform quantum information processing and coherent manipulations for atomic and molecular systems. In this paper we propose a control protocol using a tangent-pulse driven model and demonstrate that it indicates a desirable design, i.e., of being both fast and accurate for population transfer. As opposed to other existing strategies, a remarkable character of the present scheme is that high velocity of the nonadiabatic evolution itself not only will not lead to unwanted transitions but also can suppress the error caused by the truncation of the driving pulse.
