1. A circuit, comprising:
a superconducting component having a plurality of narrow portions and a plurality of wide portions;
a plurality of photon detector components, each photon detector component coupled to a corresponding narrow portion of the plurality of narrow portions and configured to provide an output that causes the corresponding narrow portion to transition from a superconducting state to a non-superconducting state; and
an output component coupled to the superconducting component, the output component configured to determine a number of the plurality of narrow portions of the superconducting component that are in the non-superconducting state.
