The development might be used to design faster quantum computers.
By destroying light in one place and recreating it remotely in another place, researchers have found a way to teleport light.
This development might be used to design faster quantum computers.
Like the classic example of Schrödinger's cat, these entangled packets of light were paradoxically "dead" and "alive" at the same time.
Researchers from Australia and Japan have successfully teleported wave packets of light, potentially revolutionizing quantum communications and computing.
The team, led by researchers at the University of Tokyo, say this is the first-ever teleportation, or transfer, of a particular complex set of quantum information from one point to another.
They say it will make possible high-speed, high-fidelity transmission of large volumes of information, such as quantum encryption keys, via communications networks.
The research appears today in the journal Science.
Professor Elanor Huntington, of the School of Engineering and Information Technology at UNSW's Canberra campus, explains that teleportation -- the transfer of quantum information from one location to another using normal, "classical" communications -- is a fundamental quantum communication technique.
