Suppressed Charge Dispersion via Resonant Tunneling in a Single-Channel Transmon
A. Kringhøj, B. van Heck, T. W. Larsen +6
We demonstrate strong suppression of charge dispersion in a semiconductor-based transmon qubit across Josephson resonances associated with a quantum dot in the junction. On resonan…
Observation of vanishing charge dispersion of a nearly-open superconducting island
Arno Bargerbos, Willemijn Uilhoorn, Chung-Kai Yang +5
Isolation from the environment determines the extent to which charge is confined on an island, which manifests as Coulomb oscillations such as charge dispersion. We investigate the…
Controlled DC Monitoring of a Superconducting Qubit
A. Kringhøj, T. W. Larsen, B. van Heck +7
Creating a transmon qubit using semiconductor-superconductor hybrid materials not only provides electrostatic control of the qubit frequency, it also allows parts of the circuit to…
End-to-end correlated subgap states in hybrid nanowires
G. L. R. Anselmetti, E. A. Martinez, G. C. Ménard +9
End-to-end correlated bound states are investigated in superconductor-semiconductor hybrid nanowires at zero magnetic field. Peaks in subgap conductance are independently identifie…
Dispersive sensing in hybrid InAs/Al nanowires
Deividas Sabonis, Eoin C. T. O'Farrell, Davydas Razmadze +4
Dispersive charge sensing is realized in hybrid semiconductor-superconductor nanowires in gate-defined single- and double-island device geometries. Signal-to-noise ratios (SNRs) we…
Fast charge sensing of Si/SiGe quantum dots via a high-frequency accumulation gate
Christian Volk, Anasua Chatterjee, Fabio Ansaloni +2
Quantum dot arrays are a versatile platform for the implementation of spin qubits, as high-bandwidth sensor dots can be integrated with single-, double- and triple-dot qubits yield…
