摘要

考虑了以热噪声和量子噪声为主要干扰的动态系统的微控制可能的精度极限。研究了基于Kalman-Bucy滤波(KBF)的最优控制和宏观目标的微观控制的物理极限。针对微物体的个体控制问题，提出了基于量子滤波方程的非爆破观测KBF的量子原型。

Physical limits and information bounds of micro control. I. Quantum filters and non-demolition measurements

The possible accuracy limit of micro control of dynamic systems in which the dominating disturbances are thermal and quantum noises is considered. The optimal control with a Kalman-Bucy filter (KBF) and physical limits of micro control of a macro object are studied. For the individual control of a micro object a quantum prototype of KBF with non-demolition observation on the basis of quantum filtering equation is introduced.
