Abstract
A low-temperature radio-frequency tuning circuit has a capacitor and an inductor. The capacitor has a capacitance between two electrodes associated with a dielectric medium, and the capacitance is tunable. The medium is a quantum paraelectric material. The capacitance is tunable by application of a voltage to apply an electric field to the medium. The capacitance is tunable at a temperature of less than 4 K by use of the quantum paraelectric material as the dielectric medium.
