theweaselkingScientists have performed successful teleportation on atoms for the first time, the journal Nature reports.
The feat was achieved by two teams of researchers working independently on the problem in the US and Austria.
It relies on a strange behaviour that exists at the atomic scale known as "entanglement", whereby two particles can have related properties even when they are far apart. Einstein called it a "spooky action".
First, a pair of highly entangled, charged atoms (or ions) are created: B and C. Next, the state to be teleported is created in a third ion, A.
Then, one ion from the pair - let's say B - is entangled with A, and the internal state of both is measured.
Finally, the quantum state of ion A is sent to ion C, transforming it. This destroys the original quantum state of A.
The teleportation took place in milliseconds and at the push of a button, the first time such a deterministic mechanism has been developed for the proces
