    Part of a larger discussion

    Challenges→Violation of λ-independence would imply the possibility of superluminal signaling in empirically adequate models of the EPR/B experiment.

    The inference from probabilistic dependence on λ-distribution to superluminal signaling illicitly assumes agent-controllability of the hidden-variable preparation, which retrocausal models deny.

    Key Terms

    Retrocausal models(as used in philosophy of time and physics)
    Theoretical frameworks that allow effects to happen backwards in time—meaning the future could influence the past, rather than only the past causing the future.
    agent-controllability(as used in philosophy of physics)
    The ability of a person or actor to control or choose something deliberately.
    hidden-variable preparation(as used in quantum mechanics)
    Setting up an experiment by controlling invisible factors (hidden variables) that might influence what happens.
    probabilistic dependence(as used in quantum physics and logic)
    When one thing's probability or likelihood depends on another thing—like how the chance of rain depends on whether it's cloudy.
    superluminal signaling

    (Discussed as a theoretical consequence of λ-distribution in certain deterministic hidden variable theories)
    The transmission of information or causal influence at speeds exceeding light, made possible if distant outcome statistics depend on a nearby controllable factor
    λ-distribution (lambda-distribution)(quantum mechanics)
    A mathematical tool (the Greek letter λ stands for 'lambda') that physicists use to represent hidden information that might explain why particles seem connected in ways we don't fully understand.
