Controlling a Fundamental Electron Property with Precisely Tuned Microwaves

Caption

A silicon sample doped with bismuth atoms (left image) that is just 150 nanometers thick is fitted with a superconducting resonator that includes a capacitor (black, in left image; light gray in center image) and an inductive wire (red line in the left image) that is 5 microns in diameter. The silicon-bismuth sample and resonator were placed in a copper box (right) and subjected to microwaves that were precisely tuned to switch an electron property, carried by the sample's bismuth atoms, on demand.
