Quantum Channel Between Earth And Space? Firing Photons Makes Advance In Space Communication (3/31/2008)

For the first time, physicists have been able to identify individual returning photons after firing and reflecting them off of a space satellite in orbit almost 1,500 kilometres above the earth. The experiment has proven the possibility of constructing a quantum channel between Space and Earth. ...> Full Article

Silicon chips for optical quantum technologies (3/28/2008)

'Superdense' coding gets denser (3/26/2008)

The record for the most amount of information sent by a single photon has been broken by researchers at the University of Illinois. Using the direction of "wiggling" and "twisting" of a pair of hyper-entangled photons, they have beaten a fundamental limit on the channel capacity for dense coding with linear optics. ...> Full Article

Stunt doubles: Ultracold atoms could replicate the electron 'jitterbug' (3/18/2008)

Ultracold atoms moving through a carefully designed arrangement of laser beams will jiggle slightly as they go, two NIST scientists have predicted.* If observed, this never-before-seen "jitterbug" motion would shed light on a little-known oddity of quantum mechanics arising from Paul Dirac's 80-year-old theory of the electron. ...> Full Article
