Physicists transfer information between matter and light

A team of physicists at the Georgia Institute of Technology has taken a
significant step toward the development of quantum communications systems by successfully transferring quantum information from two different groups of atoms onto a single photon.

The work, to be published in the October 22 issue of the journal Science, represents a "building block" that could lead to development of large-scale quantum networks. Sponsored by the Research Corporation and NASA, the work is believed to be the first to demonstrate transfer of quantum information from matter to light.
