论文摘要
量子不变的框架是对绝热量子控制的优雅概括，以控制不需要缓慢变化的控制场。由于对于具有多个空间维度的系统不可用，因此在多维系统中尚未利用该框架的好处。我们构建了一个多维高斯量子不变性，该量子不变性允许时间依赖性电势的设计，使初始电势的基态朝向最终电位的基态。该框架的范围是通过将离子围绕角落穿梭的任务来证明，这是实现被困离子量子信息技术可扩展性的范式控制问题。
The framework of quantum invariants is an elegant generalization of adiabatic quantum control to control fields that do not need to change slowly. Due to the unavailability of invariants for systems with more than one spatial dimension, the benefits of this framework have not yet been exploited in multi-dimensional systems. We construct a multi-dimensional Gaussian quantum invariant that permits the design of time-dependent potentials that let the ground state of an initial potential evolve towards the ground state of a final potential. The scope of this framework is demonstrated with the task of shuttling an ion around a corner which is a paradigmatic control problem in achieving scalability of trapped ion quantum information technology.
