<i>That&#x27;s how physicists describe it. So it is the best way.</i><p>I am not sure that this is correct. I think the usual statement is that it does not allow Alice and Bob to exchange information, not that no information exchange is involved. When Alice looks at her card and sees that it is red something happens, i.e. red as a possible colors for Bob&#x27;s card is eliminated. The wave function collapses if you want to use that picture. The state of Bob&#x27;s cards changes instantly from maybe red or maybe blue to definitely blue. One can now argue whether that change should be called information or whether the term information should be reserved for things that can be exploited by Alice and Bob but that does not change the fact that a non-local instantaneous effect changed the state of Bob&#x27;s card.<p><i>The thing to remember is that information (in physics) means &quot;particles&quot;.</i><p>That is pretty vague and might or might not be true. Do you mean every information exchanges between two spatially separated parties necessarily requires the exchange of (real) particles?<p><i>That&#x27;s the issue with QM. You would like to think that something happens.</i><p>Something happens, the wave function changes.
