量子論におけるレトロディクションII

We continue to investigate retrodictive aspects of quantum theory based on the previous paper numbered I. We now proceed to consider quantum mechanics of a single interacting particle in one-dimensional space. Under successive mearsurements of particle position and momentum as a wave packet, we argue that a piecewise approximation to the particle motion, when applicable, results in the classical retrodiction just as it results in the classical prediction.
