Abstract
A method includes generating a bias signal from a first device, and applying the bias signal to a second device, the first device having (a) a superconducting trace and (b) a superconducting quantum interference device (SQUID), in which a first terminal of the SQUID is electrically coupled to a first end of the superconducting trace, and a second terminal of the SQUID is electrically coupled to a second end of the superconducting trace, where generating the bias signal from the first device includes: applying a first signal Φ1 to a first sub-loop of the SQUID; and applying a second signal Φ2 to a second sub-loop of the SQUID, in which the first signal Φ1 and the second signal Φ2 are applied such that a value of a superconducting phase of the first device is incremented or decremented by a non-zero integer multiple n of 2π.
