为了严格描述某些测量过程，在整个时间间隔内观察量子到达计数器，有必要引入量子随机过程的概念。虽然完全量子力学的性质，这些有很大的相似之处，经典的随机过程，并可以通过其无穷小生成器的特点和建设。无穷小生成元自然是从某些我们证明必须是玻色子或费米子类型的“场”中得到的。
In order to describe rigorously certain measurement procedures, where observations of the arrival of quanta at a counter are made throughout an interval of time, it is necessary to introduce the concept of a quantum stochastic process. While fully quantum mechanical in nature, these have a great deal of similarity with classical stochastic processes and can be characterized by and constructed from their infinitesimal generators. The infinitestimal generators are naturally obtained from certain “fields” which we prove must be of the boson or fermion type.
