查询词典 probability

In this scheme, the description of unitary evolution and quantum measurement is unified and the quantum control operation is represented by probability state transition. The algorithm works as follows. At first a measurement is applied on the system. If the state after collapse is not the desired eigenstate, then system evolution will go on. After a period of time, the system is measured again. The process will go on like this until we get the desired eigenstate by measurement. Finally the system is driven to the target state with admissible control as before.

4把本征态能控性概念进一步向前发展，提出了概率能控性的概念，将幺正演化和量子测量这两种量子控制手段统一的用概率状态转移来描述，并针对一类特殊的本征态能控的系统，提出了幺正演化和测量交替进行的量子反馈控制策略：如果单步测量所得到的本征态不是期望的本征态，则让系统以这一本征态作为新的初态进行下一步的幺正演化，然后在适当的时候再次测量，让系统塌缩到某一本征态，如此重复进行，直到达到期望的目标态为止。

These episodes in individual tales display such striking regularities in aggregate that some of the social scientists who first applied the rules of probability to human affairs questioned the very notion of free will."Society prepares the crime," wrote Adolphe Quetelet, a Belgian statistician, in 1835,"and the guilty person is only the instrument."

这些互相独立的故事中的一幕幕情节都显示出惊人的规律性（这些相互独立的故事都有着惊人相似的情节），因此，那些最早将概率法则应用于分析人类事件的社会科学家们颇为质疑所谓的自由意愿这个概念。1835年，比利时统计学家阿道夫·凯特勒（注1）曾写道，"人类社会酝酿了罪行，犯罪的个体只是工具罢了。"
