Quantum Theory of Observers
Jose L Balduz
Abstract
This is an attempt to create a consistent and non-trivial extension of quantum theory, describing in detail the quantum measurement process. A tentative but concrete model is presented, based on the concept of multiple observer/participators, represented by separate state vectors. The evolution is deterministic, and in the chaotic regime implies approximate adherence to the Born rule for probabilities. The model is applied in a number of contexts: simple detectors, multi-state selectors, and intermittent systems. The results are consistent with phenomenology. We also consider more speculative applications, including specific spin and position `observables.' Finally the outlook for the model is discussed, and its relation to other work.
