In accordance with the present invention, a superconducting phase shift
device is presented. The phase shift device can introduce a phase shift
between the phases of the order parameters of the device's two terminals.
The two terminals can be coupled through an anisotropic superconductor
with angled sides, or through two anisotropic superconductors with
misaligned phases, or through a ferromagnet in the junction area. The
phase shift device can be used in superconducting quantum computing
circuitry. A method of fabricating the phase shift device with a
technology different from fabrication technology of conventional
superconducting materials is described. A method for fabricating a phase
shifter chip including an array of phase shift devices is described.
