Two-Worlds Interpretation of Quantum MechanicsThe stochastic nature of quantum mechanics is more naturally reflected in abilinear two-process representation of density matrices rather than in squaredwave functions. This proposition comes with a remarkable change of theentanglement mechanism: entanglement does not originate from superpositions ofwave functions, but results from the bilinear structure of density matrices.Quantum interference is not an additive superposition mechanism, but rather amultiplicative phenomenon. The proposed bilinear representation of densitymatrices is given in terms of two stochastic jump processes. These ideas areillustrated for the Einstein-Podolsky-Rosen and double-slit experiments. Theexpression of the stochastic nature of quantum mechanics in terms of randomvariables rather than their probability distributions facilitates anontological viewpoint and leads us to a two-worlds interpretation of quantummechanics.arxiv.org
