关于量子测量投影公设的动力学解释

On the Dynamical Interpretation for the Quantum-Measurement Projection Postulate

R. L. Stratonovich, V. P. Belavkin

摘要:

考虑了一种适合于该问题精确解的具有离散动量空间的装置模型。它与所考虑的对象系统的相互作用的特殊的哈密顿量被选择。在这个简单的例子中,很容易说明,在构造选择性坍缩的动力学解释时的困难是如何在没有任何限制程序的情况下被克服的。为了这个目的,人们可以应用关于非量子参数的平均或减少联合系统算子的代数(即。e.传递到量子系统子代数)。后一个过程实际上意味着相对于不属于系统的装置量子变量进行平均。

英文摘要:

An apparatus model with discrete momentum space suitable for the exact solution of the problem is considered. The special Hamiltonian of its interaction with the object system under consideration is chosen. In this simple case it is easy to illustrate how difficulties in constructing the dynamical interpretation of selective collapse could be overcomed without any limiting procedure. For this purpose one can apply either averaging with respect to a non-quantum parameter or reducing the algebra of the joint system operators (i. e. passing to the quantum system subalgebra). The latter procedure effectively implies averaging with respect to apparatus quantum variables not belonging to the system.
