Abstract
Starting with unitary quantum dynamics, we investigate how to add quantum measurements. Quantum measurements have four essential components: the furcation, the witness production, an alignment projection, and the actual choice decision. The first two components still lie in the domain of unitary quantum dynamics. The decoherence concept explains the third contribution. It can be based on the requirement that witnesses reaching the end of time on the wave function side and the conjugate one have to be identical. In this way, it also stays within the quantum dynamics domain. The surjection hypothesis explains the actual choice decision. It is based on a two boundary interpretation applied to the complete quantum universe. It offers a simple way to reduce these seemingly random projections to purely deterministic unitary quantum dynamics, eliminating the measurement problem.

IntroductionPublisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations
One can argue that the time is ripe for solving the fundamental problem with quantum mechanic (QM) measurements
We investigate how to add measurements and define four components. We observe that both setup components lie in the domain of quantum dynamics
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Experimental observations of quantum effects are available, exceeding by far what the founders considered possible. They involve individual particles and reach regions that were considered a safe, purely classical refuge. In the last 100 years, many ideas about quantum measurements were pursued, and there is an enormous amount of publications They are, not always of good quality and sometimes involve overstated opinions. The aim is to stay simple and avoid unessential formalism even where it is well developed [1] This will allow us to discuss various interpretations in a rather neutral way and, to present our advocated surjection interpretation.
