For those thinking that this is a step towards faster-than-light (FTL) communication: As far as I know it's fairly certain that quantum entanglement will not allow for FTL communication. Basic principle is that while measurements between both sides will be correlated, it's not possible to tell <i>how</i> they are correlated until both sides compare measurements.<p><a href="https://en.wikipedia.org/wiki/Superluminal_communication#Quantum_nonlocality" rel="nofollow">https://en.wikipedia.org/wiki/Superluminal_communication#Qua...</a><p><a href="http://physics.stackexchange.com/a/203893" rel="nofollow">http://physics.stackexchange.com/a/203893</a><p>Given that, it seems like the touted benefit of using quantum entanglement here is in securing communications, since your measurements will no longer correlate if a third party is also measuring? At least, that's what I gathered.
