Scientists Teleport Information Between Ions a Meter Apart 220
erickhill writes with word that scientists from the University of Maryland have successfully transferred information from one charged atom to another without having it cross the intervening space of about one meter. The academic paper is available in the journal Science, though it requires a subscription to see more than the abstract.
Scientists have previously teleported unmolested qubits between photons of light, and between photons and clouds of atoms. But researchers have long sought to teleport qubits between distant atoms. Light's high speed of travel makes photons good transporters of information, but for storing quantum information, atoms are a much better choice because they're easier to hold on to. 'This is a big deal,' comments Myungshik Kim, a quantum physicist at Queen's University Belfast in the United Kingdom. 'To store information as it is in quantum form, you have to have a teleportation scheme available between two stationary qubits. Then you can store them and manipulate them later on.'"

In breaking news, the molester has been ordered to both sign and not sign the Atomic Sexual Deviancy Register at the same time.

It's like sending someone an encrypted message over an insecure channel. Great until you realize you now have to send him the key over the same channel. Sure it's encrypted, but the means of making it useful renders it ineffective.
Sure you can, you just need to use public key encryption. So I guess you're saying we need public key quantum entanglement?
Just kidding, thanks for the clarification. :)

Analogy:
I have two basket balls, one has a cat inside - I don't know which one.
I send one basket ball to you.
I open my basket ball (observation).
I find it empty so I can deduce the cat is in yours (no information is transfered to you).
I cannot tell if you have opened yours and observed the cat as dead or alive.
You open yours and find a dead cat (observation).
Information is transfered in the normal manner when you call me up and ask why I sent you a dead cat in a basketball.

More importantly, does this kind of teleportation make the same cool sound as the teleportation the original "Star Trek"?
