Quantum teleportation

Maybe in a few decades we'll be able to teleport bigger things; but for now, light. From a National Geographic article:

"Austrian researchers have teleported photons (particles of light) across the Danube River in Vienna using technology that calls to mind Scotty beaming up Captain Kirk in the science fiction series."

and

"The researchers read the "blueprints" of the photons they wanted to teleport. They then broke up the photons into smaller particles called quantum bits and sent these bits, along with the blueprints, through a fiber-optic cable in a sewage pipe under the river.

At the other end, replicas of the original photons were created. The original photons ceased to exist once the replicas were created."
