We theoretically exploit the shortcuts to adiabaticity (STA) technique in Hermitian and non-Hermitian quantum systems to realize the maximum coherence and beam splitting by eliminating the nonadiabatic coupling. Compared with the conventional adiabatic passage (AP) technique with the Gaussian and Allen-Eberly schemes, the operation time can be significantly shortened by three order using STA technique. This STA-based fast creation of maximum coherence or beam splitting are in use ranging from quantum sensing and metrology in a noisy environment to optical gain/loss coupled waveguides in an analogous fashion.

绝热的埃尔米特和非埃尔米特捷径，可快速创建最大相干性和分束

从理论上讲，我们利用Hermitian和非Hermitian量子系统中的绝热（STA）技术的捷径，通过消除非绝热耦合来实现最大的相干性和分束。与采用高斯和Allen-Eberly方案的传统绝热通道（AP）技术相比，使用STA技术可将操作时间显着缩短三阶。这种基于STA的最大相干性或分束器快速创建方法正在使用，范围从嘈杂环境中的量子感测和计量学到类似方式的光增益/损耗耦合波导。
