Physicists set a new teleportation record:

Teleportation goes long distance

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. The team has published its findings in the academic journal Nature.

Researchers from the University of Vienna and the Austrian Academy of Science used an 800m-long optical fibre fed through a public sewer system tunnel to connect labs on opposite sides of the River Danube.

It’s a long way from “Beam me up, Scotty,” (or even, “Digitize me, Fred!”), but it’s still pretty cool.
