Frequency shift of quantum computing elements

Abstract

According to one embodiment, an apparatus for frequency shifting of quantum computing elements includes a plurality of persistent current loops, each persistent current loop being couplable to a corresponding quantum computing element, a first plurality of signal lines, each persistent current loop being coupled to a corresponding signal line of the first plurality of signal lines, and a second plurality of signal lines, each persistent current loop being coupled to a corresponding signal line of the second plurality of signal lines, each persistent current loop being configured to induce a persistent current in the persistent current loop in response to a pulse in a corresponding signal line of the first plurality of signal lines and / or a corresponding signal line of the second plurality of signal lines, the persistent current being configured to cause a shift in the frequency of the corresponding quantum computing element.
