Magnetic Phase Shifter for Superconducting Qubits

Dušan S. Golubović, W. V. Pogosov, Mathieu Morelle +1 more

We have designed and investigated a contactless magnetic phase shifter for flux-based superconducting qubits. The phase shifter is realized by placing a perpendicularly magnetized dot at the center of a superconducting loop. The flux generated by this magnetic dot gives rise to an additional shielding current in the loop and induces a phase shift. By modifying the parameters of the dot an arbitrary phase shift can be generated in the loop. This magnetic phase shifter can, therefore, be used as an external current source in superconducting circuits, as well as a suitable tool to study fractional Josephson vortices.

Nonlinear Delay Line Phase Shifters for Terahertz Superconductive Electronic Circuits.

Malcom R. Beasley, H. J. Snortland

Abstract : We report on the development of an electrically controllable superconducting phase shifter suitable for operation in a terahertz heterodyne receiver. The key physical principle of operation, and that of nonlinear kinetic inductance, is developed into a device theory and also appropriate design rules. Critical figures of merit are then identified and optimized designs presented. Experimental tests of prototypes are described that were used to help further refine the design rules. Although a practical phase shifter was not produced, the prospects for the device concept appear good. Terahertz, Phase-Shifter, Nonlinear, Kinetic Inductance, Superconducting.
