Claim 7:
8. A method for performing parametric amplification with a kinetic inductance parametric amplifier comprising the step of:
providing a kinetic inductance parametric amplifier comprising: an input port arranged to receive a pump tone, a DC bias and an input signal; an output port arranged to provide an amplified version of the input signal; a tunable stepped-impedance assembly comprising a bandstop filter arranged to attenuate and/or filter predetermined frequency bands; and a high kinetic inductance line; wherein the tunable stepped-impedance assembly is tuned at a frequency that allows for the kinetic inductance parametric amplifier to resonate at a predetermined frequency and wherein the pump tone has a frequency higher than the frequency of the input signal and the DC bias signal is transmitted to the high kinetic inductance line;
applying a DC signal configured to modify the kinetic inductance and one or more filtering properties of the stepped-impedance assembly;
applying the pump tone and the input signal to the input port; and
detecting the amplified version of the input signal at the output port.
