Abstract: A system includes a first superconducting wire and a second superconducting wire connected in parallel. The system includes a first current source coupled to the first superconducting wire and configured to supply a first current in response to a trigger event. The system includes a second current source coupled in series with the parallel combination of the first superconducting wire and the second superconducting wire and configured to supply a second current. The superconducting wires are configured to, while receiving the second current, operate in a superconducting state in the absence of the first current. The first superconducting wire is configured to, while receiving the second current, transition to a non-superconducting state in response to the first current. The second superconducting wire is configured to, while receiving the second current, transition to a non-superconducting state in response to the first superconducting wire transitioning to the non-superconducting state.

Abstract: An electric circuit includes a first superconducting component, a second superconducting component, a first electrically-insulating component that thermally couples the first superconducting component and the second superconducting component such that heat produced in response to the first superconducting component transitioning to a non-superconducting state is transferred through the first electrically-insulating component to the second superconducting component, and a photon detector coupled to the first superconducting component. The photon detector is configured to output a first current to the first superconducting component upon detection of a threshold number of photons. The electric circuit further includes an output component coupled to the second superconducting component. The output component is configured to be responsive to a voltage drop across the second superconducting component.
