Improving the proof of the Born rule using a physical requirement on the dynamics of quantum particles

Abstract

AbstractWe propose a complete proof of the Born rule using an additional postulate stating that for a short enough time $$\Delta t$$ Δ t between two measurements, a property of a particle will keep its values fixed. This dynamical postulate allows us to produce the Born rule in its explicit form by improving the result given in [1]. While the proposed postulate is still not part of the quantum mechanics postulates, every experiment obeys it, and it cannot be deduced using the standard postulates of quantum mechanics.
