Quantum non-locality based on finite-speed causal influences leads to superluminal signalling
Abstract

Non-local quantum correlations between distant particles cannot be explained by signals propagating slower than the speed of light. It is now shown that they cannot be explained by hidden influences propagating faster than the speed of light either, because that would permit faster-than-light communication.
