Comment on `Quantum resolution to the arrow of time dilemma'

TL;DR

This paper critiques a proposed quantum solution to the arrow of time dilemma, showing the argument is incomplete and providing a counter-example, ultimately suggesting quantum mechanics enhances classical memory of entropy-decreasing events.

Contribution

It identifies gaps in the existing quantum resolution proposal and offers a counter-example demonstrating its incorrectness.

Findings

The argument for quantum resolution is incomplete.

Counter-example shows the proposal is incorrect.

Quantum mechanics can enhance classical memory records.

Abstract

Recently, a substantial amount of debate has grown up around a proposed quantum resolution to the `arrow of time dilemma' that is based on the role of classical memory records of entropy-decreasing events. In this note we show that the argument is incomplete and furthermore, by providing a counter-example, argue that it is incorrect. Instead of quantum mechanics providing a resolution in the manner suggested, it allows enhanced classical memory records of entropy-decreasing events.
