An electric circuit includes a plurality of superconducting components, each of the plurality of superconducting components having: a respective first terminal; a respective second terminal; and a respective input. The electric circuit further includes a bias current source electrically-connected to the respective first terminal of each of the plurality of superconducting components. The bias current source is configured to provide a bias current adapted to cause the electric circuit to function as a logical OR gate on the respective inputs of the plurality of superconducting components. The electric circuit further includes an output node adapted to output a state of the logical OR gate.
