# Quantum phenomena modelled by interactions between many classical worlds

@article{Hall2014QuantumPM, title={Quantum phenomena modelled by interactions between many classical worlds}, author={Michael J. W. Hall and Dirk - Andr'e Deckert and Howard M. Wiseman}, journal={Bulletin of the American Physical Society}, year={2014}, volume={2015} }

We investigate whether quantum theory can be understood as the continuum limit of a mechanical theory, in which there is a huge, but finite, number of classical "worlds," and quantum effects arise solely from a universal interaction between these worlds, without reference to any wave function. Here, a "world" means an entire universe with well-defined properties, determined by the classical configuration of its particles and fields. In our approach, each world evolves deterministically… Expand

Quantum mechanics as a deterministic theory of a continuum of worlds

- Physics

A non-relativistic quantum mechanical theory is proposed that describes the universe as a continuum of worlds whose mutual interference gives rise to quantum phenomena. A logical framework is… Expand

Quantum mechanics as a deterministic theory of a continuum of worlds

The theory explains (1) the subjective occurrence of probabilities, (2) their quantitative value as given by the Born rule, and (3) the apparently random “collapse of the wavefunction” caused by the measurement, while still being an objectively deterministic theory. Expand
