Abstract
One or more systems, devices, methods of use and/or methods of fabrication provided herein relate to a superconducting device that can be operated with minimal electric field energy coupling at surface layers of the superconducting device and/or that can have a small footprint. According to one embodiment, a device can comprise a Josephson junction located between a first capacitor portion and a second capacitor portion of a capacitor, wherein at least a trenched section of the first capacitor portion is located beneath a surface of a substrate, and wherein at least a trenched section of the second capacitor portion is located beneath the surface of the substrate. According to another embodiment, a device can comprise a capacitor disposed within a substrate layer and the capacitor comprising a pair of material-filled trenches in the substrate layer, and a Josephson junction coupled to the capacitor.
