This is pretty scary. A cross-app method that uses manufacturing imperfections in RAM.

Unfortunately, that’s not how that works. Quantum mechanics doesn’t break the laws of physics, is was simply that previous observations were not precise enough to observe quantum effects and the models we used before were incorrect because of that. As for quantum entanglement, see this for a better explanation than I can give.

Basically the takeaway is that messages can’t be passed through entanglement faster than light because it requires knowledge known by the sender to actually decode the sent message.
