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,” says Carlton Caves of the University of New Mexico.
