Scientists have managed to make a copy of a beam of laser light, combining quantum cloning with quantum teleportation. And that sounds mighty cool. But once you get past this article's Star Trek references, you get to what seems to be the real reason for the research:"Quantum cryptographic protocols are so secure that they can not only discover tapping but also where and how much information is leaking out. Now, using telecloning, the identity and location of the eavesdropper can be concealed."And that's a good thing?
