I'm not a physicist and the paper is paywalled so I'm speculating, but the speed of light in this crystal is probably much lower than the speed of light in a vacuum, and it's the latter that puts an uppper limit on the rate at which information can propagate (excluding quantum entanglement).
- TeMPOraL 13y ago> excluding quantum entanglement IANAP either, but AFAIK (ah, acronyms :)) quantum entanglement can not transfer information FTL.
- alcari 13y agoI'm also not a physicist, but as I understand it entangled particles can affect each other instantaneously regardless of distance, but cannot transfer information due to random instabilities.
- nbouscal 13y agoIIRC it's not due to random instabilities, but rather due to the no cloning theorem: http://en.wikipedia.org/wiki/No-cloning_theorem http://en.wikipedia.org/wiki/No-cloning_theorem
