Beam me up


A LIGHT beam is the latest thing to find itself transported across a lab as scientists strive towards the sci-fi dream of teleporting. In the past year, two separate teams of physicists have managed to teleport the quantum state of a single photon across a lab bench. Now an international team of physicists has teleported a light beam across a table top, by transporting the amplitude and phase of the light and transferring that information onto another beam (Science, vol 282, p 706). “It’s oscillating up and down, and they transmit the size of the oscillations and the zero-crossings,
