Kinetic Inductance Traveling Wave Amplifiers For Multiplexed Qubit Readout
Leonardo Ranzani, Mustafa Bal, Kin Chung Fong +7
We describe a kinetic inductance traveling-wave (KIT) amplifier suitable for superconducting quantum information measurements and characterize its wideband scattering and noise pro…
Variational theory of the tapered impedance transformer
R P Erickson
Superconducting amplifiers are key components of modern quantum information circuits. To minimize information loss and reduce oscillations a tapered impedance transformer of new de…
Theory of Multiwave Mixing within the Superconducting Kinetic-Inductance Traveling-Wave Amplifier
Robert P. Erickson, David P. Pappas
We present a theory of parametric mixing within the coplanar waveguide (CPW) of a superconducting nonlinear kinetic-inductance traveling-wave (KIT) amplifier engineered with period…
Low-noise kinetic inductance traveling-wave amplifier using three-wave mixing
Michael R. Vissers, Robert P. Erickson, Hsiang-Sheng Ku +4
We have fabricated a wide-bandwidth, high dynamic range, low-noise cryogenic amplifier based on a superconducting kinetic inductance traveling-wave device. The device was made from…
Ultra-Broadband Microwave Frequency-Comb Generation in Superconducting Resonators
R. P. Erickson, M. R. Vissers, M. Sandberg +2
We have generated frequency combs spanning 0.5 to 20 GHz in superconducting half wave resonators at T=3 K. Thin films of niobium-titanium nitride enabled this development due to th…
