Can the study of reduction probabilities reveal news about the nature of quantum state reduction?

TL;DR

This paper introduces a phenomenological model for calculating quantum state reduction probabilities based on mutual physical interactions, with applications to gravitational reduction hypotheses and potential implications for biology and quantum non-locality.

Contribution

It presents a new model for reduction probabilities that depends solely on mutual interactions, extending the gravitational reduction hypothesis and proposing experimental tests.

Findings

Model agrees with the projection postulate in typical experiments

Predicts new regimes with different behavior

Proposes a feasible quantum optical experiment for verification

Abstract

A phenomenological model for the calculation of reduction probabilities of a superposition of several states is presented. The approach bases only the idea that quantum state reduction has its origin in a mutual physical interaction between the states. The model is explicitly worked out for the gravitational reduction hypothesis of Diosi and Penrose. It agrees for typical quantum mechanical experiments with the projection postulate and predicts regimes in which other behavior could be observed. An outlook is given, how the new effects can possibly become of interest for biology. For verification a feasible quantum optical experiment is proposed. The approach is analyzed from the view point of quantum non-locality in concrete its consequences for signalling.
