    Antony Valentini wrote: “First and foremost, as I said in my answer to Question 1, before I studied de Broglie-Bohm theory properly, I was very puzzled by why we can’t use quantum
    nonlocality for signalling. It was as if there was some sort of conspiracy at work in the laws of physics. To explain this, I had drawn the conclusion that we were stuck in some sort of statistical equilibrium state whereby uncertainty noise happens to mask the underlying nonlocal effects (a kind of equilibrium ‘balancing’ condition, as I had vaguely thought of it).”

    We are not stuck. We are precisely the kind of sub-quantum non-equilibrium system you seek.
    This is evidenced by the brain presponse experiments by Ben Libet cited by Roger Penrose and since replicated in at least three independent studies by Dean Radin, Dick Bierman and Daryl Bem. We also have Henry Stapp’s analysis of Helmut Schmidt’s data.

    AV: “When I studied pilot-wave theory
    and saw that it was a consistent theory, I was amazed to see that it provided a precise realisation of what I had been looking for: it was a nonlocal theory, for which the nonlocality was washed out or averaged to zero in the state of ‘quantum
    equilibrium’ – the state in which the hidden configurations have a Born-rule distribution. Other people working on the theory usually took the Born probability rule as an axiom, alongside the equations of motion, but to me it seemed
    obvious that the theory should be considered for arbitrary distributions. I was able to show that such distributions give rise to nonlocal signals at the statistical level. I also proved an analogue of the classical coarse-graining H -theorem, which
    gave a general understanding of how evolution towards equilibrium occurs for an isolated system, as has since been confirmed by numerical simulations.”

    Dead matter is in thermal equilibrium, living matter is not (necessary not sufficient condition). I think the kind of post-quantum theory Valentini is looking for with signaling entanglement violating orthodox quantum theory is found in living matter.

    AV: “It seemed natural to me to suppose that relaxation to equilibrium had taken place in the
    remote past, presumably soon after the big bang. The nonlocality associated with early nonequilibrium might then explain why the early universe was so homogeneous. More importantly, the puzzle of why we can’t use quantum nonlocality
    for signalling could be given a simple answer: it’s a peculiarity of the fact that we happen to be stuck in an equilibrium state. There’s no conspiracy in the laws of physics, we are simply trapped in a special state with special properties. Both
    signal-locality and the uncertainty principle could be shown to be contingencies of equilibrium.”

    However, there is a door out of the box.

    AV: “This viewpoint opens up the possibility of a new and wider ‘non equilibrium’ physics, in which superluminal signalling is possible and the uncertainty principle can be circumvented. Relativity, too, is violated in this new physics, which contains a notion of absolute simultaneity associated with a preferred state of rest.”

    This last idea is no longer needed as shown by R. I. Sutherland.

    “A version of Bohm’s model incorporating retrocausality is presented, the aim being to
    explain the nonlocality of Bell’s theorem while maintaining Lorentz invariance in the
    underlying ontology. The strengths and weaknesses of this alternative model are
    compared with those of the standard Bohm model.”
