Abstract
An integrated circuit is provided that comprises a first ground plane associated with a first set of circuits that have a first operational temperature requirement, and a second ground plane associated with a second set of circuits that have a second operational temperature requirement that is higher than the first operational temperature requirement. The second ground plane is substantially thermally isolated from the first ground plane. A superconducting coupler electrically couples the first ground plane and the second ground plane while maintaining relative thermal isolation between the first ground plane and the second ground plane.
