Teleportation is defined as the production, disembodiment and successful reconstruction of a signal.
Latest research involves the use of crystals, lenses and mirrors to produce a pair of “entangled” laser beams that are then used to carry fragile information in the form of quantum states.
What the team’s find boils down to is that, using a laser, they can teleport to a network of recipients a signal which can only be reassembled by a majority of the recipients. Any less and the signal cannot be reconstituted.
The team’s leader, Chinese-born Ping Koy Lam, was building on work done by the university in 2002, when they teleported information using a laser beam.
But Ping described the latest achievement as “a much more complex form of information teleportation in the sense that it involves multiple recipients”.
