Exceeding the Parametric Drive Strength Threshold in Nonlinear Circuits
Mingkang Xia, Cristóbal Lledó, Matthew Capocci +7
Superconducting quantum circuits rely on strong drives to implement fast gates, high-fidelity readout, and state stabilization. However, these drives can induce uncontrolled excita…

Josephson parametric amplifier with Chebyshev gain profile and high saturation
Ryan Kaufman, Theodore White, Mark I. Dykman +10
We demonstrate a Josephson parametric amplifier design with a band-pass impedance matching network based on a third-order Chebyshev prototype. We measured eight amplifiers operatin…
