swansont Posted July 15, 2019 Share Posted July 15, 2019 ...despite the headline saying they did https://time.com/4854718/quantum-entanglement-teleport-space/? Some stories say they teleported an electron. This one says photon. Regardless, it was the state of the particle that was teleported, not the particle itself. 1 Link to comment Share on other sites More sharing options...
MigL Posted July 15, 2019 Share Posted July 15, 2019 (edited) Is that even an accurate statement ? the 'state' of a particle is information; as such it cannot be 'teleported', but must obey locality. Edited July 15, 2019 by MigL Link to comment Share on other sites More sharing options...

Are they using hyperbole to make it sound more exciting? Edited July 16, 2019 by Curious layman Link to comment Share on other sites More sharing options...

Locality is not violated. The information transfer happens no faster than c 3 hours ago, Curious layman said: That's very confusing.

If e.g. an electron is spin up, you transmit the information that it's spin up and make an electron at the destination be spin up. But you can do this without knowing the state of the particle.

MigL Posted July 16, 2019 Share Posted July 16, 2019 "The information transfer happens no faster than c" Exactly ! so why call it 'teleportation', which implies instantaneous transfer across undefined distance ? Link to comment Share on other sites More sharing options...

MigL Posted July 16, 2019 Share Posted July 16, 2019 (edited) My post was in reply to Swansont who claimed that just the 'state' was teleported, not the particle. The 'state' is information, and as such, cannot be teleported. ( at least according to my understanding of what 'teleportation' means; or am I being pedantic ? ) Edited July 16, 2019 by MigL Link to comment Share on other sites More sharing options...
J.C.MacSwell Posted July 16, 2019 Share Posted July 16, 2019 (edited) Wow...so you're saying they've done it more than once? Now I'll read the OP and the article... Edited July 16, 2019 by J.C.MacSwell Link to comment Share on other sites More sharing options...
QuantumT Posted July 16, 2019 Share Posted July 16, 2019 (edited) So they entangled two particles while they were hundreds of miles apart? Mind blowing! But hey... it's from 2017! Why address this now? Edited July 16, 2019 by QuantumT Link to comment Share on other sites More sharing options...

Didn't notice it was from 2017; I thought I was getting ahead of the curve in pushing back on the dodgy pop-sci headline. Link to comment Share on other sites More sharing options...
