Tim Maudlin: Prospects for Superluminal information Transfer Using Quantum Non-Locality

Tim Maudlin, professor of philosophy at NewYork University in the USA delivered a speech on "Prospects for Superluminal information Transfer Using Quantum Non-Locality" during the "Frontiers in Foundations of Physics: A Philosophical Inquiry" conference held online on 2023 May 18-19th.

the point i simply forgot to mention is that in the limit of instantaneous action, a time operator is useless, but in a theory not in that limit, where there are travel times for the influences controling the variable dependence you must have something like a time operator, and it might be possible if settings are set at the outset to use them, depending on the theory that departs from instantaneous action to use them or other variables to communicate as long as some scheme is set up ahead of time. although i have not reviewed these proposals carefully in the context as of yet because much work remains to nail down the theory itself.

excelent presentation. the commutation of the operator is irrelevant, because the commutation of the operators are stricktly speaking about the dependence of the averages of outcomes, you have to ask whether there is a dependence between variable upon measurement, and then ask about the theoretical properties of such a description. for every two choices of measurements of abell pair, either side will get a 50% 50% outcome, so if im in lab A i can do nothing to influence what you will see in the other lab B. in a theory like an objective collapse theory, where the collapse is global and instantaneous, there is no communication allower from it even though i can easily control your measurment outcome in the following way, i can control if i know your choice of axis, whether i get the same outcome as you but flipped for example, or how randomized your outcome is compared to mine in my lab, i have full control over that, but i cannot control which direction of spin i will see in my lab after choosing an axis, but if i know which axis you will choose i can make sure it is perfectly correlated with my outcome if i wish, or completely randomized at a different angle say 90% off. so if i know which axis you choose ahead of time, ican litterally control your outcomes in a spesific way, but only in relation to my outcome. so the end result is that on your side, if you cannot communicate with me already i cannot send you any information, because no matter what axis you choose you will get a coin toss of up and down. that doesnt mean the influence i can control cannot in other cases be used to transfer information, but that requires having a theory of this influence, such that it can be derived and tested, with the current theory, we do not know where it is wrong, we do not know if there is a velocity limited effect controlling this influence and so on. we need a theory, im working on it, but it takes some time for a lazy dog .

Zero prospects. There. Saved you over an hour of Tim Maudlin listening to Tim Maudlin speaking. ;-)

@@schmetterling4477 you have me stumped. Anyways, he does propose a single example of a prospect… he doesn’t argue for its possibility or reality or anything else… it’s just a prospect
