# On Non-Linear Quantum Mechanics and the Measurement Problem IV. Experimental Tests

## TL;DR

This paper reviews three proposed experiments aimed at identifying the quantum-classical boundary and differentiating between Hamiltonian and spontaneous-collapse theories of quantum mechanics.

## Contribution

It introduces experimental approaches to test non-linear quantum mechanics and distinguish it from collapse models, advancing understanding of the measurement problem.

## Key findings

- Proposes experiments to locate the quantum-classical boundary
- Suggests methods to differentiate Hamiltonian and collapse theories
- Provides theoretical groundwork for future experimental validation

## Abstract

I discuss three proposed experiments that could in principle locate the boundary between the classical and quantum worlds, as well as distinguish the Hamiltonian theory presented in the first paper of this series from the spontaneous-collapse theories.
