back to article Single chip photon source brings quantum comms closer

Down at the “basic research” level, there's a lot the labs can accomplish with quantum mechanics: entanglement, information teleportation, simple quantum computations and more. Now, an international collaboration believes it's brought exploitation of quantum effects closer to a commercial development. The researchers have …

As I understand it * ....

... you can't use entanglement to send information between two places instantaneously (in the sense of sending a bit stream representing the letter 'A', for example), but you can use it to send information between two places (at the speed of photons) in such a way that nobody can intercept or listen in to the data transfer without the end parties being aware that this is happening. Hence its potential for use in very secure data networks.

*From snippets of info I read or heard somewhere.

Yeah, I've heard of quantum teleportation before but I'm pretty sure they specifically said it couldn't be used to transmit information. Where's the author getting this from?
