Suppose we try to explain quantum correlations by postulating that as soon as one member of an entangled pair of particles is measured, a very fast signal travels to its partner, updating its state. If the signal is instantaneous, then such a model is indistinguishable from quantum theory. But what if the signal is fast, but not infinitely fast? Salart and collaborators establish a lower bound on the speed of any such signal (it must be &gt; 10,000 times the speed of light). But we have to be careful about which reference frame is used to define the velocity. Natural choices, such…</p><p><a href="https://hackerpaper.kaipfister.de/p/quant-ph_0002031/">Paper and discussion history</a>. A mention is not an endorsement.</p>quant-ph
