Fragile Systems: A hidden variable theory for quantum mechanics

By Yasmin Navarrete and Sergio Davis


The formalism of Quantum Mechanics is derived from the application of Bayesian probability theory to "fragile" systems, i.e. systems that are perturbed by the act of measurement. Complex Hilbert spaces, non-commuting operators and the trace rule for expectations all arise naturally from the use of linear algebra to solve integral equations involving classical probabilities over hidden variables. We comment on the case of non-local hidden variables, where violations of Bell's theorem can be produced, as well as the non-fragile limit of the theory, where all measurements are commutative and the theory becomes analogous to classical statistical mechanics.Comment: 4 page
