Deep link? The two fields both contain the notion of locality, big woop. The application of quantum nonlocal correlations to game theory is interesting, but this is not what is advertised in the article. I am displeased.
The journalistic article isn't worth reading. I don't have access to the real paper, but it should be more interesting and informative.
In addition, your statements "quantum-entangled systems can transfer information useful to game players" is wrong, or at least misleading. Entangled particles can't communicate information any better than classical methods. (Well, unless you're concerned about privacy, but that's a whole other issue which doesn't effect the game...)
Actually, with the aid of entangled particles, there's also superdense coding, which allows for two-bits-per-qubit coding (i.e. information density well beyond the classical limit).
Though I'm not sure what your metric for "better" is here, coding density seems to be mildly reasonable. OTOH, this isn't related at all to the article at hand, just a fun application of entanglement :D
