Creation and vanishing of superposition states

TL;DR

This paper presents a unified framework for understanding how superposition states are formed and disappear during quantum measurements, addressing the problem of definite outcomes in quantum mechanics.

Contribution

It introduces conditions under which a combined system evolves into, maintains, or loses superposition states, providing insights into measurement outcomes.

Findings

Conditions for superposition formation identified

Mechanisms for superposition decline analyzed

Implications for quantum measurement problem discussed

Abstract

The evolution of a measured system and an experimental apparatus is presented in an unified form. Conditions under which the state of such a total system forms, evaluates and declines from a superposition of states are defined. The problem of definite outcomes in the quantum-mechanical measurement theory is considered.
