Comparing optical-microwave conversion and all-microwave control schemes for a transmon qubit
Volodymyr Monarkha, Massimo Borrelli, Reza Hajitashakkori Kenari +13
We report a comparative study on transmon qubit control using (i) conventional attenuated coaxial microwave line and (ii) an optical control system using modulated laser light deli…
Equivalence of flexible stripline and coaxial cables for superconducting qubit control and readout pulses
V. Y. Monarkha, S. Simbierowicz, M. Borrelli +11
We report a comparative study on microwave control lines for a transmon qubit using: (i) flexible stripline transmission lines, and (ii) semi-rigid coaxial cables. During each expe…
Microwave calibration of qubit drive line components at millikelvin temperatures
Slawomir Simbierowicz, Volodymyr Y. Monarkha, Suren Singh +3
Systematic errors in qubit state preparation arise due to non-idealities in the qubit control lines such as impedance mismatch. Using a data-based methodology of short-open-load ca…
Overlap junctions for superconducting quantum electronics and amplifiers
Mustafa Bal, Junling Long, Ruichen Zhao +10
Due to their unique properties as lossless, nonlinear circuit elements, Josephson junctions lie at the heart of superconducting quantum information processing. Previously, we demon…
