Description:
The quantum measurement problem: why a unique outcome is obtained in each individual experiment, is currently tackled by solving models. After a general introduction, we review the many models proposed. Next, a flexible and realistic quantum model is introduced, describing the measurement of the z-component of a spin through interaction with a magnetic memory simulated by a Curie-Weiss magnet, including N >>1 spins coupled to a phonon bath.
