我们提出了几个无参数化的解决方案，通过连续测量和光滑量子反馈的量子态约简控制的问题。特别是，我们设计了一个反馈律，几乎全局随机反馈镇定可以证明分析通过李雅普诺夫techinques。这种综合非常自然地产生于问题的物理学，因为它依赖于与量子滤波过程相关的方差。
We propose several parametrization-free solutions to the problem of quantum state reduction control by means of continuous measurement and smooth quantum feedback. In particular, we design a feedback law for which almost global stochastic feedback stabilization can be proved analytically by means of Lyapunov techinques. This synthesis arises very naturally from the physics of the problem, as it relies on the variance associated with the quantum filtering process.
