Abstract
One example includes a superconducting circuit. The circuit includes superconducting circuitry fabricated in a circuit layer. The circuit layer includes a first surface and a second surface opposite the first surface. The circuit also includes a flux moat comprising a dielectric material formed in the circuit layer. The flux moat can be configured to trap a magnetic flux as the superconducting circuit is cooled to below a superconducting critical temperature. The circuit further includes a magnetic film arranged proximal to the flux moat on at least one of the first and second surfaces of the circuit layer. The magnetic film can be configured to guide the magnetic flux to the flux moat as the superconducting circuit is cooled to below the superconducting critical temperature.
