Austrian Physicists 'Teleport' Light Over 600m

openSoar writes "The BBC is reporting that: 'Physicists have carried out successful teleportation with particles of light over a distance of 600m across the River Danube in Austria. When physicists say 'teleportation', they are describing the transfer of key properties from one particle to another without a physical link.'"

The researchers were able to teleport three distinct polarisation states between Alice and Bob via the fibre-optic cable through the tunnel. The process is not instantaneous as it is limited by the speed of light.

I am feeling particularly stupid, I guess... But wouldn't the fibre-optic cable exist to transfer the entangled photons and the "spooky action at a distance" be performed between the entangled photons regardless of the existance of the fibre-optic cable?

What does the cable have to do with this other than making sure both sides have an entangled photon?

These folks did not "teleport" a single particle, they transferred the _properties_ of some particles to particles elsewere. Those properties were transported with the about the speed of light. So, I don't see
quite how you could apply this to humans in the sence of teleporting an entire human somewhere else.
