In defense of real quantum theory
J. Finkelstein
TL;DR
This paper critiques recent claims that complex numbers are essential for quantum theory, defending the viability of real quantum theory as a consistent alternative.
Contribution
It provides a critical analysis of recent arguments favoring complex quantum theory, supporting the validity of real quantum theory.
Findings
Complex numbers are not strictly necessary for quantum theory
Real quantum theory can be a consistent framework
Recent claims for the necessity of complex numbers are challenged
Abstract
Two recent papers (Renou et al., arXiv:2101.10873, and Chen et al., arXiv:2103.08123) have indicated that complex numbers are necessary for quantum theory. This short note is a comment on their result.
