1. A programmable circuit, comprising:
a superconducting component arranged in a multi-dimensional array of alternating narrow and wide portions, the superconducting component having an input terminal and an output terminal;
an electrical source coupled to the input terminal;
a readout circuit coupled to the output terminal; and
control circuitry coupled to respective narrow portions of the multi-dimensional array of alternating narrow and wide portions, the control circuitry configured to:
operate the superconducting component in a first programmed state by maintaining a first subset of the narrow portions in a non-superconducting state; and
operate the superconducting component in a second programmed state, distinct from the first programmed state, by maintaining a second subset of the narrow portions in the non-superconducting state.
