Having read this very carefully, I can't see how quantum mechanics as I always understood it can ever be either non-local or break relativity. The following was probably written down by someone else a long time ago, but I don't know by who or when.

When you entangle two systems, they have to actually be in the same place/with slower-than-light communication distance. Thus, they each store "secret" information in some deterministic way which is impossible to measure directly, and which we can probe only using repeated experiments and probability distributions. The idea is that while quantum systems are deterministic just like mechanical ones, they hide their determinism in black boxes whose mechanisms it is impossible to discover. The "uncollapsed waveform" has in fact been collapsed ahead of time, you just don't know what the answer is until you measure.

Back to our entangled particles, when you separate them the determined decision they made when they were together is revealed. They do not need to communicate, as they already have their story straight.

It seems this entire area of research is a misnomer - if you let the prisoners talk to each other just after arrest, of course their stories will be complimentary later, even if one is in Alcatraz and the other in Siberia. You just have to assume that particles so small we can only "see" them in the way they interact with other particles have some internal structure/state that we also can't see, and thus like the prisoners, can remember the story.

(of course, declaring an entire area of research irrelevant is usually a sign that I've missed the point wildly - if anyone would like to correct my mistake I'd be interested to hear!)
