| Description |
JQI researchers think they have discovered a way to amplify faint electrical signals using the motion of a nanomechanical membrane, or loudspeaker. If shown in experiments, the scheme could prove a boon to magnetic resonance imaging and quantum information science. This schematic of the proposed device shows its use in detecting--in this example--a signal produced by the quantum-mechanical "spin" of a group of atoms. The atoms generate a faint radiofrequency signal in a coil (L) which is connected to microscale wires that form an electrical capacitor. This vibrates the 'nanomembrane' which in turn affects the resonant frequency of a laser optical cavity. The output is light at frequency that is the sum of the original laser frequency plus the signal from the atoms.
