Problems of Probability Theory in the Light of Quantum Mechanics

Antoine Soulas

Endeavoring to formulate an exhaustive solution to the measurement problem in view of the theory of decoherence leads to a better understanding of the status of the collapse and of the emergence of classicality, thanks to a precise definition of the measurement and some new vocabulary to speak about quantum mechanics. Considering the latter as a probabilistic theory all along allows us to avoid the usual probability problem of the many-worlds interpretations. A thorough verification of the consistency of quantum mechanics at all scales is proposed, as well as a discussion of what can be deemed an observer.

In the study of light transmision and absorption in quantum mechanics, it can'it get satisfactory results to explain the external e. m. field by classical treatment. For example, it can't explain why the stimulated waves are in the same as the stimulating waves in frequency, phase, polarizing state and propagation-direction, etc. the probability of spontaneous radiation-transition can't be obtained directly from the theories of quantum mechanics, unless we draw support from Einstein's phenomenological theory. Especially, the first problem is the foundation of laser theories, and such a problem in normal quantum mechanics and laser theories has not been solved thoroughly. So in this paper we present a full quantum mechanical proof, i. e. to explain both the particals and e. m. field by quantizing treatment, so as to get a quite satisfactory result.

A number of books have appeared purporting to explain quantum mechanics to the general public. These books have put considerable emphasis on so-called quantum 'paradoxes', using them to portray the quantum theory as mysterious or 'spooky'. The author discusses these 'paradoxes' from a different viewpoint with the aim of demystifying the theory. Emphasis is shifted from an epistemological viewpoint (as exemplified by the 'probability interpretation') to an ontological one (the description of matter by physical fields). Difficulties in reconciling the probability interpretation with relativity are noted, and the importance of phase coherence, which is inadequately treated in the probability interpretation, is emphasised. In the light of such as approach, the 'paradoxes' are resolved.
