“…To characterize uniquely the classical trajectories of individual fragments, an experiment must be designed to define the final vector position and vector momentum of that particle. If only position or only momentum is measured, for example, then more than one trajectory can contribute to the wave function and give rise to interference, as is well documented with neutron and atom interferometry [7][8][9]. However, each factor contributing to the interference can still be assigned to a particular trajectory.…”

The mechanism of the transition of a dynamical system from quantum to classical mechanics is of continuing interest. Practically it is of importance for the interpretation of multi-particle coincidence measurements performed at macroscopic distances from a microscopic reaction zone. Here we prove the generalized imaging theorem which shows that the spatial wave function of any multi-particle quantum system, propagating over distances and times large on an atomic scale but still microscopic, and subject to deterministic external fields and particle interactions, becomes proportional to the initial momentum wave function where the position and momentum coordinates define a classical trajectory. Currently, the quantum to classical transition is considered to occur via decoherence caused by stochastic interaction with an environment. The imaging theorem arises from unitary Schrödinger propagation and so is valid without any environmental interaction. It implies that a simultaneous measurement of both position and momentum will define a unique classical trajectory, whereas a less complete measurement of say position alone can lead to quantum interference effects.

“…The large field of neutron optics and neutron interferometry has been omitted in our work, because it can be found in [10]. Neutron interferometry experiments are also discussed in a review on 'Neutron interferometry' [11]. Much of the literature on quantum interference phenomena has been covered in that work.…”

“…This suggests that some sort of multivalued logic should be used and that "False" is not the same as "Not True." Moreover an experiment to determining through which hole the neutron goes interferes so strongly with the neutron that the axiom of additivity is restored [24].…”

We review and discuss first briefly the algebraic framework of classical and quantum physics and commutative and noncommutative probability theory. After that we propose a mathematical definition of decoherence sufficiently general to accommodate quantum systems with infinitely many degrees of freedom and give an exhaustive list of possible scenarios that can emerge due to decoherence. We conclude with some messages of quantum science.
