Remarks on the Relativistic Transactional Interpretation of Quantum Mechanics
Louis Marchildon
TL;DR
This paper discusses the Relativistic Transactional Interpretation of quantum mechanics, examining its approach to the measurement problem and unitarity, and critiques a specific proposal addressing nonunitarity.
Contribution
It provides a critical analysis of RTI's handling of unitarity and challenges a proposal on the origin of nonunitarity within this interpretation.
Findings
RTI offers a clear definition of absorbers and addresses the measurement problem.
The paper finds flaws in a specific proposal linking nonunitarity to the origin of measurement.
RTI's stance on unitarity is examined but not definitively resolved.
Abstract
Kastner (arXiv:1709.09367) and Kastner and Cramer (arXiv:1711.04501) argue that the Relativistic Transactional Interpretation (RTI) of quantum mechanics provides a clear definition of absorbers and a solution to the measurement problem. I briefly examine how RTI stands with respect to unitarity in quantum mechanics. I then argue that a specific proposal to locate the origin of nonunitarity is flawed, at least in its present form.
