Integrated Quantum Device (IMAGE) University of Chicago Caption This scanning electron microscope image of an integrated quantum device shows a mechanically suspended crystal (blue) with metal electrodes (yellow) and a semiconductor photonic circuit (red). The scale bar at upper left measures 10 microns, much less than the diameter of a human hair. The device seamlessly transfers signals between optical and electrical quantum states, which have significantly different characteristics.
