开放量子系统的随机控制

Randomized control of open quantum systems

Lorenza Viola

摘要:

研究一般开放量子系统的开环动力学控制问题。特别是,我专注于有效地关闭负责不必要的退相干和耗散效应的环境耦合的任务。在重新访问通过确定性控制动态解耦的标准框架,我描述了一种不同的方法,即控制器有意获得一个随机组件。给出了随机解耦最坏性能的显式误差界。

英文摘要:

The problem of open-loop dynamical control of generic open quantum systems is addressed. In particular, I focus on the task of effectively switching off environmental couplings responsible for unwanted decoherence and dissipation effects. After revisiting the standard framework for dynamical decoupling via deterministic controls, I describe a different approach whereby the controller intentionally acquires a random component. An explicit error bound on worst-case performance of stochastic decoupling is presented.
