Nature (July 27) – Researchers have proposed a quantum experiment aboard the International Space Station that would simultaneously entangle the states of two separate properties of a photon – a technique known as hyperentanglement – to make teleportation more reliable and efficient. As well as making communications much more secure, satellite systems would mark a major step toward a “quantum internet” made up of quantum computers around the world, or a quantum computing cloud, says Paul Kwiat, a physicist at Illinois who is working with NASA on the ISS project.
