US Patent 12119820 Superconducting field-programmable gate array

A programmable circuit includes a superconducting multi-dimensional array. The programmable circuit further includes a plurality of photon detectors coupled to respective portions of the superconducting multi-dimensional array, each photon detector configured to selectively provide input to a corresponding respective portion sufficient to transition the corresponding respective portion from a superconducting state to a non-superconducting state. The programmable circuit also includes one or more electrical terminals coupled to respective second portions of the superconducting multi-dimensional array.
