From Rebecca Boyle at PopSci.com, we learn, “Researchers Succeed in Quantum Teleportation of Light Waves: Like Schrödinger’s cat, teleported light is both dead and alive” (04.15.2011)
In this experiment, researchers in Australia and Japan were able to transfer quantum information from one place to another without having to physically move it. It was destroyed in one place and instantly resurrected in another, “alive” again and unchanged. This is a major advance, as previous teleportation experiments were either very slow or caused some information to be lost.The team employed a mind-boggling set of quantum manipulation techniques to achieve this, including squeezing, photon subtraction, entanglement and homodyne detection. The photo above depicts their device, nicknamed the Teleporter, in the lab of Akira Furusawa at the University of Tokyo.
The results pave the way for high-speed, high-fidelity transmission of information, according to Elanor Huntington, a professor at the University of New South Wales in Australia who was part of the study.
This one looks like it might be true. What are the practical uses?
