1. A three-dimensional superconducting qubit comprising:
a structural base comprising one or more insulating materials; and
at least two superconductive patterns on at least three surfaces of the structural base, including a first surface, a second surface, and a third surface, the at least two superconductive patterns forming at least a capacitive part and an inductive part of the three-dimensional superconducting qubit,
wherein the first surface of the structural base defines a first plane having a similar orientation as that of a top surface of the structural base,
wherein the second surface of the structural base defines a second plane that is oriented differently than the first plane,
wherein the third surface of the structural base defines a third plane that is oriented differently than the first plane and the second plane, and
wherein a first pattern of the at least two superconductive patterns extends from the first surface to the second surface and a second pattern of the at least two superconductive patterns extends from the first surface to the third surface.
