Quantum State Reduction by a Physical Interaction Between the States and its Perspective for Biology

Garrelt Quandt-Wiese


A phenomenological model for the calculation of reduction probabilities of a superposition of several states is presented, which bases only the idea that quantum state reduction has its origin in a physical interaction between the states. The model is explicitly worked out for the hypothesis of gravity-induced quantum state reduction. It agrees for typical quantum mechanical experiments with the projection postulate and predicts regimes in which other behaviour could be observed. For verification a feasible quantum-optical experiment is proposed. An outlook on the possible role of state reduction for biology is given by exemplarily discussing mutation effects of bacteria.
