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.

    • It is possible to make quantitative statements that I think capture many of the intuitions you assert. Here was one attempt: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.10... That particular proposal was mathematically wrong for reasons I still find physically…
