I'm guessing it's in terms of quantum information. Quantum entanglement and tunneling can happen faster than the speed of light, which causes similar time paradoxes with special relativity. This is avoided by the impossibility of sending observable classical information. Two entangled objects can affect each other, but you can't get actual information about it, because it is destroyed upon observation.
