On the derivation of reduction from the Schrodinger equation. A disproof of no-go theorems and a proposal

TL;DR

This paper challenges existing no-go theorems by explicitly constructing macroscopic devices within quantum mechanics, proposing a scheme to derive wave function reduction from fundamental principles, thus suggesting potential consistency.

Contribution

It disproves no-go theorems by incorporating device organization and proposes a new scheme to derive wave function reduction from quantum mechanics.

Findings

No-go theorems are invalidated when device organization is considered.

A scheme for deriving wave function reduction from quantum principles is proposed.

Explicit construction of macroscopic devices supports the possibility of fundamental consistency.

Abstract

The possibility of a fundamental consistency between the basic quantum principles and reduction (so-called wave function reduction) is reexamined. The mathematical description of an organized macroscopic device is constructed explicitly as a convenient tool for this investigation. Previous no-go theorems excluding consistency are disproved on this ground, because their assumptions neglected the occurrence of organization in a real measuring apparatus. A scheme for deriving reduction from quantum mechanics is also proposed as a conjecture.
