Remember a few months back when photons were successfully teleported? Well, they’ve done it with atoms now.
In quantum teleportation, the sender, normally called Alice, instantaneously transfers information about the quantum state of a particle to a receiver called Bob. The uncertainty principle means that Alice cannot know the exact state of her particle. However, another feature of quantum mechanics called “entanglement” means that she can teleport the state to Bob.
I’m not real sure what all that means, but I’m sure that soon they’ll be able to do this with multiple atoms at the same time. I think we’ve all seen The Fly enough times to understand how many ways this technology can go wrong.
If they’re going to start building Star Trek contraptions, let’s start with a holodeck. Wouldn’t you rather your garage looked like the moon than risk a trip to the moon in a teleporter?
