M2 PRESSWIRE-2 February 2007-YALE UNIVERSITY: Artificial Atoms Make Microwave Photons Countable(C)1994-2007 M2 COMMUNICATIONS LTD RDATE:01022007 New Haven, Conn. -- Using artificial atoms on a chip, Yale physicists have taken the next step toward quantum computing by demonstrating that the particle nature of microwave photons can now be detected, according to a report spotlighted in the February 1 issue of the journal Nature.

Quantum theories are often considered to apply best to processes that happen on the smallest scale of atoms and molecules. By making artificial atoms larger -- to a size that is nearly visible -- and using microwaves as the source of energy, the collaborative research from the laboratory of Professor Robert Schoelkopf and the theory...
