JQI cool nano loudspeakers could makes for better MRIs, quantum computers

(PhysOrg.com) -- A team of physicists from the Joint Quantum Institute (JQI), the Neils Bohr Institute in Copenhagen, Denmark, and Harvard University has developed a theory describing how to both detect weak electrical signals and cool electrical circuits using light and something very like a nanosized loudspeaker. If demonstrated through experiment, the work could have a tremendous impact on detection of low-power radio signals, magnetic resonance imaging (MRI), and the developing field of quantum information science.
