That's what Einstein argued for, and it's what Bell's inequality proves to not be the case.
I actually remember seeing a Youtube video of Susskind talking about how "FTL" communication is a hack to try to force the quantum state to conform with our notions about the world. (he didn't phrase it this way though; just my interpretation).
I don't know the context it was said, but it seemed to imply that there's a way of thinking about quantum states completely independent of set theory and our classical notions, and this way of thinking should not require FTL communication between entangled particles.
Edit:
I think this was the video: https://www.youtube.com/watch?v=xT1bm1yM8Ow https://www.youtube.com/watch?v=xT1bm1yM8Ow
He seems to imply that Aspect's experiment negates hidden/FTL communication.
- evanb 12y agoWhile GP's example is not what happens in QM (Bell's inequality shows that the state of the two coins is not predetermined-but-secret), it is akin to that example, in the sense that because each person gets a random (though correlated) bit, they cannot transmit information to one another. Bell's inequality is a statement about the possible strength of the correlation, rather than about information transmission.
