Researchers quantum teleport particle of light six kilometres
I posted this in a duplicate thread:<p>For those thinking that this is a step towards faster-than-light (FTL) communication: As far as I know it&#x27;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&#x27;s not possible to tell <i>how</i> they are correlated until both sides compare measurements.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Superluminal_communication#Quantum_nonlocality" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Superluminal_communication#Qua...</a><p><a href="http:&#x2F;&#x2F;physics.stackexchange.com&#x2F;a&#x2F;203893" rel="nofollow">http:&#x2F;&#x2F;physics.stackexchange.com&#x2F;a&#x2F;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&#x27;s what I gathered.
