SYSTEMS AND METHODS FOR CONTROLLING QUANTUM COMPONENTS

Programmable components of a quantum processor may be selectively programmed using digital to analog converters (DACs). A DAC with a first stage and a second stage and first and second quantum flux parametron (OFF) loops galvanically coupled to and extending from a respective one of the first stage...

Beschreibung
Zusammenfassung:	Programmable components of a quantum processor may be selectively programmed using digital to analog converters (DACs). A DAC with a first stage and a second stage and first and second quantum flux parametron (OFF) loops galvanically coupled to and extending from a respective one of the first stage and the second stage is discussed. The first stage has a first storage loop interrupted by a first Josephson junction and an interface for communicating with an external component. The second stage has a second storage loop interrupted by a second Josephson junction, the second storage loop galvanically coupled to the first storage loop, the first Josephson junction and the second Josephson junction coupled in series to a first control line. A method of loading flux quanta into targeted DAC stages is also discussed.
