A group of University of Wisconsin–Madison physicists has identified conditions under which relatively distant atoms communicate with each other in ways that had previously only been seen in atoms closer together—a development that could have applications to quantum computing.

The physicists' findings, published Oct. 14 in the journal Physical Review A, open up new prospects for generating entangled , the term given to atoms that share information at large distances, which are important for quantum communications and the development of quantum computers.
