Readout-Induced Leakage in Superconducting Circuits with Nonlinear Couplings
Sumeru Hazra, Wei Dai, Daniel K. Weiss +3
In superconducting circuits, drive-induced unwanted transitions limit the readout power, thereby constraining readout speed and fidelity. When such transitions excite the qubit int…
Rhenium as a material platform for long-lived transmon qubits
Yanhao Wang, Suhas Ganjam, Ishan Narra +2
Dielectric loss at the interfaces of superconducting films has long been recognized as limiting the performance of state-of-the-art superconducting circuits. Notably, the presence…
Characterization of drive-induced unwanted state transitions in superconducting circuits
W. Dai, S. Hazra, D. K. Weiss +11
Microwave drives are essential for implementing control and readout operations in superconducting quantum circuits. However, increasing the drive strength eventually leads to unwan…
Lumped-element broadband SNAIL parametric amplifier with on-chip pump filter for multiplexed readout
V. R. Joshi, S. Hazra, A. Z. Ding +7
We present a SNAIL-based parametric amplifier that integrates a lumped-element impedance matching network for increased bandwidth and an on-chip pump-port filter for efficient pump…
