From physicsworld.com: headline news:
A new technique for controlling the speed of "teleportation" in quantum systems has been created by physicists in the US and UK. The team has demonstrated a way of "tuning" beams of light to distribute quantum information to specific points in space and time. Manipulating and storing data in this way is an important step towards new communication devices and eventually a quantum computer, say the researchers.
In quantum teleportation, the sender (Alice) instantaneously transfers the quantum state of a particle to a receiver (Bob). In 1997 physicists captured public attention by teleporting quantum states between "entangled" photons for the first time. Entanglement is a feature of quantum mechanics that allows particles with two distinct quantum states to share a much closer relationship than classical physics allows.
Over the intervening 12 years teleportation has been demonstrated over increasing distances and between larger particles.
