The elusive dream of quantum computing might seem far off, but researchers everywhere are trying to figure out solutions to get us closer to these powerful computers. One team of scientists from the University of Toronto has succeeded in making an important tool in computing, a logic gate, from a single atom. It uses clever optical effects to transmit information. The research is published in Nature Physics.
