摘要
量子绝热过程是制备和操控量子态的常用方法之一, 通常其需要较长的操作时间, 会引起退相干系统中操作保真度的快速下降。量子绝热捷径技术理论上可以通过抵消演化过程中的非绝热效应来实现对量子绝热过程的加速。当应用于受激拉曼绝热转移中时, 量子绝热捷径技术可以实现既快又好的量子操控。概述了量子绝热捷径技术的基本概念及实验进展, 重点介绍了其在受激拉曼绝热转移中的应用。
Abstract
Quantum adiabatic process is one of general ways to prepare and manipulate the quantum states, which usually needs long operation time and makes the manipulation fidelity drop fast in a dephasing system. Theoretically, the technology of quantum shortcut to adiabaticity is proposed to eliminate the non-adiabatic effects during its evolution, which can speed up the quantum adiabatic process. When the technology of quantum shortcut to adiabaticity is applied in the stimulated Raman adiabatic transfer, it can realize the fast and robust quantum control. The basic concept of the technology of quantum shortcut to adiabaticity and its experimental progress are summarized, and its application in the stimulated Raman adiabatic transfer is emphatically introduced.
