Teleportation goes long distance

From The BBC

Physicists have carried out successful teleportation with particles of light over a distance of 600m across the River Danube in Austria.

Long distance teleportation is crucial if dreams of superfast quantum computing are to be realised.

When physicists say "teleportation", they are describing the transfer of key properties from one particle to another without a physical link.


This also has important implications for secure communications. With quantum communications you will know if someone "read" your message because that will alter the quantum state of those communications.
