I need to catch up on my quantum physics, every time I read that someone pulled off quantum teleportation I'm disappointed when I read the line "here we realize quantum teleportation between two remote atomic-ensemble quantum memory nodes, each composed of 100 million rubidium atoms and connected by a 150-meter optical fiber" taken from the source article. http://arxiv.org/abs/1211.2892 http://arxiv.org/abs/1211.2892
I know there's a difference between what they did and regular fiber optics. It just doesn't seem to be quite the same. Can it be done without the interconnecting material? If not it's really useless. When I picture practical uses of quantum teleportation I picture things like rovers instantly sending data and receiving instructions.

It's impossible to transmit classical information faster than light via quantum teleportation. You don't necessarily have to have "interconnecting material", but there will always have to be a classical information channel, and that will always be light-speed bound.
- jakeonthemove 14y agoI don't think it's useless. As I understand, quantum teleportation would allow for a massive increase in bandwidth. That's a pretty good result, and who knows, maybe they'll get rid of the interconnecting cables in the future, as well.
