I'm in the process of coming up with a straight-forward full-proof test of no-signalling.stay tuned

Exciting!

Want to see a *non-local* simulation that matches QM and all required conditions? It goes like this

- Code: Select all
`Repeat N times`

Pick two settings a, b however you like

Pick two outcomes x, y from the joint probability distribution p(x, y | a, b) according to QM's EPR-B model.

Sorry, but in case you did not know, QM does not permit signalling like that. You can't use (a,b) together at any station to obtain outcomes. Otherwise, Alice and Bob can easily communicate using entanglement, which is forbidden. Go back to the drawing board.

Nope. Even with Richard's model, there is no way that Alice can signal to Bob (or vice versa) by using detector settings. No matter what setting Alice chooses, the probability distribution on Bob's end will still be 50/50. And of course if you had known even a whiff about quantum mechanics you would know that entanglement requires a distribution that depends on both a and b, but still is consistent with the no-signalling theorem.
