What does it take to solve the measurement problem?

TL;DR

This paper reviews the quantum measurement problem, argues it is a genuine issue requiring a solution, and critiques existing interpretations for failing to resolve it, while discussing potential benefits of solving it.

Contribution

It clarifies the properties needed for a theory to solve the measurement problem and critiques current interpretations for their inability to do so.

Findings

No current interpretation fully solves the measurement problem

The measurement problem is a genuine issue in quantum mechanics

Understanding the problem could lead to significant theoretical advances

Abstract

We summarise different aspects of the measurement problem in quantum mechanics. We argue that it is a real problem which requires a solution, and identify the properties a theory needs to solve the problem. We show that no current interpretation of quantum mechanics solves the problem, and that, being interpretations rather than extensions of quantum mechanics, they cannot solve it. Finally, we speculate what a solution of the measurement problem might be good for.
