Nonsense. The same would have been asserted regarding on-off binary messaging. When two entangled particles react, as in some change in one instantly changes the other, THAT IS COMMUNICATION.
No. If two entangled particles are observed, there is a correlation between the pure states observed, which will be random (in the odd sense of quantum randomness in which complex amplitudes behave like probabilities in terms of multiplying, but the likelihood of an event is the magnitude of the amplitude). The correlation between them is not preserved in interactions, since one is then considering a larger quantum system including the particles they are interacting with, and the states that are relevant are the states of the larger system, not just the entangle pair.
It’s not usable communication. You can’t transmit usable information through that means, so how is it communication?
