Many of the contemporary formulations of quantum mechanics describe the marginal probability distributions of entangled many-body systems in a non-local way. Unlike the non-locality of joint distributions, the non-locality of marginal distributions is not forced by theory or experiment. This paper investigates the issue in the context of the Copenhagen, de Broglie-Bohm and sum-over-paths interpretations. A dissociation between information flow into quantum subsystems and the tensor product structure of wavefunctions is highlighted in connection to the problem.

  1. On the causal efficacy of qualia: Philosophical zombies are fine-tuned, and implications for the quantum measurement theory

    quant-ph 2025-02 reject novelty 4.0 of 10

    Conscious experiences are claimed to steer quantum branch selection, making philosophical zombies statistically unlikely and proposing initial-condition sensitivity as a test for consciousness.
