A transmon qubit realized by exploiting the superconductor-insulator transition
C. G. L. Bøttcher, E. Önder, T. Connolly +8
Superconducting qubits are among the most promising platforms for realizing practical quantum computers. One requirement to create a quantum processor is nonlinearity, which in sup…
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…
Exact Duality at Low Energy in a Josephson Tunnel Junction Coupled to a Transmission Line
Luca Giacomelli, Michel H. Devoret, Cristiano Ciuti
We theoretically explore the low-energy behavior of a Josephson tunnel junction coupled to a finite-length, charge-biased transmission line and compare it to its flux-biased counte…
