Findings

Quantum postulates can be derived from discrete measurement assumptions

Measurement interactions influence the system in a fundamental way

The approach offers a more intuitive understanding of quantum mechanics

Abstract

Quantum mechanics is usually presented starting from a series of postulates about the mathematical framework. In this work we show that those same postulates can be derived by assuming that measurements are discrete interactions: that is, that we measure at specific moments in time (as opposed to a continuous measurement that spans a long time interval) and that the system is in general affected by our measurement. We believe that this way of presenting quantum mechanics would make it easier to understand by laying out a more cohesive view of the theory and making it resonate more with our physics intuition.
