Abstract
An example photon counting device includes one or more unit cells. Each unit cell includes one or more superconducting components. Each unit cell also includes a current dynamics control element coupled in series with the one or more superconducting components. Each unit cell further includes a transistor having a superconducting gate element that is coupled with the one or more superconducting components and a channel element that is electrically insulated from the superconducting gate element, where the channel element has a first resistance while the superconducting gate element is in a superconducting state and a second resistance while the superconducting gate element is in a non-superconducting state. The photon counting device further includes a bias current source coupled to the one or more unit cells and a waveguide optically coupled to the one or more unit cells.
