Using Sound to Remember Quantum Information (IMAGE)
Caption
A team of Caltech scientists has fabricated a superconducting qubit on a chip and connected it to a tiny device that scientists call a mechanical oscillator. Essentially a miniature tuning fork, the oscillator consists of flexible plates that are vibrated by sound waves at gigahertz frequencies. When an electric charge is placed on those plates, the plates can interact with electrical signals carrying quantum information. This allows information to be piped into the device for storage as a "memory" and be piped out, or "remembered," later. Here, a scanning electron microscope image highlighting a single mechanical oscillator from the new work. The false-colored golden lines in the image indicate the location of electrodes that transfer electrical signals between the superconducting qubit and the mechanical oscillator.
