System Characterization of Dispersive Readout in Superconducting Qubits
Daniel Sank, Alex Opremcak, Andreas Bengtsson +4
Designing quantum systems with the measurement speed and accuracy needed for quantum error correction using superconducting qubits requires iterative design and test informed by ac…
Measurement of small photon numbers in circuit QED resonators
Juan Atalaya, Alex Opremcak, Ani Nersisyan +2
Off-resonant interaction of fluctuating photons in a resonator with a qubit increases the qubit dephasing rate. We use this effect to measure a small average number of intracavity…
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…
