简介：为在连续测量的影响下面的一个N维的量系统，这份报纸论述控制法律枪战影片类型并且分别地完成一个非退化、退化的测量操作符的任意地给定的eigenstate的asymptotic准备的一个切换的控制计划。在切换的控制策略，我们把州的空间划分成二部分：包含一个目标状态的一个集合，和它的互补集合。由在考虑下面分析随机的系统模型的稳定性，我们设计一条经常的控制法律并且给控制Hamiltonian满足的一些条件以便在互补集合的系统轨道收敛到包含目标状态的集合。为一个非退化的测量操作员的盒子，进一步，我们证明在包含状态将自动地集成到目标的目标的集合的系统轨道经由量说连续测量理论；当时为一个退化测量操作符的盒子，相应系统轨道将也经由控制Hamiltonians的构造收敛到目标状态。在盒子下面的整个靠近环的系统的集中一非退化并且一个退化测量操作员严格地被证明。建议切换的控制计划的有效性被一个有限维的尖动量系统和一个two-qubit系统的模拟实验验证。
