I mean it's a photon, but still (BBC news) (www.bbc.com)

From what I read yesterday it's not what we think of as teleportation. They didn't make it disappear here on Earth and reappear in space. -- (edited) - Krusty Jul 12, 07:18 5
- I supposed the technical description is "quantum teleportation" which as I understand it transfers the state (ie: information) between two entangled - oblique Jul 12, 07:25 4
  - "spooky action at a distance". -- nm - Reagen Jul 12, 07:46
  - That's what I got from my reading which is to say I kind of understood what they were saying but not really. :-) - Krusty Jul 12, 07:27 2
    - yeah. this is one of those areas where I'm completely lost in the "why" of it but I'll accept the "what" -- nm - oblique Jul 12, 07:29 1
      - Yup. :-) -- nm - Krusty Jul 12, 07:30

I read that last night. Might lead to super fast encrypted communications networks that beam signals across the globe at light speed. - Bacon Jul 12, 07:14 6
- Hmm. I thought quantum entanglement was "instant", which would imply FTL? - Beryllium Jul 12, 07:32 5
  - I think this is the theory, but it hasn't been tested in practice yet. -- nm - Roger More Jul 12, 07:40 3
    - Except, the Millennium Falcon travels at .5 passed light speed. -- nm - Bacon Jul 12, 07:43 2
      - 25,000 light-years per day or 1,041.66 light-years per hour. That's a top speed of 2.74 x 1015 meters per second. -- nm - Spawn Jul 12, 07:45 1
        
        I'm guessing that should be 10^15? -- nm - Beryllium Jul 12, 07:53
  - In this case, the way I read it, it's light speed. But I would love your scenario to be true. -- nm - Bacon Jul 12, 07:35
