Superconducting impedance matched parametric amplifier

An apparatus for determining a superconducting impedance matched parametric amplifier, the apparatus comprising:

• processing circuitry configured to:
• determine a center wavelength parameter, a gain parameter, and a bandwidth parameter of the superconducting impedance matched parametric amplifier based on an operating environment of a quantum chip;
• determine an impedance value of an impedance matching line of the superconducting impedance matched parametric amplifier and a capacitance value of the amplifier based on the wavelength parameter, the gain parameter, and the bandwidth parameter as constraints;
• calculate a line width dimension of a coplanar waveguide of the superconducting impedance matched parametric amplifier based on the impedance value of the impedance matching line;
• calculate a stub dimension of the superconducting impedance matched parametric amplifier based on the impedance value of the impedance matching line and the capacitance value of the amplifier;
• and
• determine structural parameters of the superconducting impedance matched parametric amplifier based on the line width dimension and the stub dimension.
