More Teleportation?

It won’t be coming any sooner than the last time I mentioned researchers teleporting atoms but researchers in Australia have proposed a way to teleport atoms from one location to another.

The full paper is available here as well as an animated description here.

What differentiates our scheme from what is usually termed quantum teleportation is that our scheme does not require the sender and receiver to share entangled states, as there is no measurement step involved in sending the information.

In this scheme the sender and receiver require a reservoir of extremely cold atoms, known as a Bose-Einstein condensate (BEC).

BEC is a state of matter that occurs when atoms become very cold, (about 100 billionths of a degree about absolute zero).

Due to a phenomenon known as Bose-Enhancement, all the atoms like to act the same way. This causes the atoms to act as one macroscopic matterwave, rather than a collection of individual atoms.
