摘要:

量子信息技术要求对量子系统进行高度精确的控制。实现这一点需要控制技术,尽管存在的散肩噪声和其他不利影响,表现良好。在这里,我们回顾了一个通用的技术,用于设计控制领域,动态地纠正错误,同时使用量子演化和几何空间曲线之间的密切关系进行操作。这种方法提供了访问的全局解决方案空间的控制字段,完成一个给定的任务,方便设计实验可行的门操作的各种应用。

英文摘要:

Quantum information technologies demand highly accurate control over quantum systems. Achieving this requires control techniques that perform well despite the presence of decohering noise and other adverse effects. Here, we review a general technique for designing control fields that dynamically correct errors while performing operations using a close relationship between quantum evolution and geometric space curves. This approach provides access to the global solution space of control fields that accomplish a given task, facilitating the design of experimentally feasible gate operations for a wide variety of applications.
