1. A superconducting circuit element comprising:
a room temperature (RT) superconducting circuit element comprising:
a thin film, with one or more circuit element openings, disposed on a rigid substrate, the thin film selected from the group consisting of a piezoelectric thin film and a ferroelectric thin film; and
an under compression room temperature (UC-RT) superconductor material disposed within the one or more circuit element openings such that actuation of the thin film applies a compressive stress on the UC-RT superconductor material and the RT superconducting circuit element is formed on the rigid substrate.
