Offset Charge Dependence of Measurement-Induced Transitions in Transmons
Mathieu Féchant, Marie Frédérique Dumas, Denis Bénâtre +9
A key challenge in achieving scalable fault tolerance in superconducting quantum processors is readout fidelity, which lags behind one- and two-qubit gate fidelity. A major limitat…

Simultaneous sweet-spot locking of gradiometric fluxonium qubits
Denis Bénâtre, Mathieu Féchant, Nicolas Zapata +4
Efforts to scale up superconducting processors that employ flux-qubits face numerous challenges, among which is the crosstalk created by neighboring flux lines, which are necessary…

Pure kinetic inductance coupling for cQED with flux qubits
Simon Geisert, Soeren Ihssen, Patrick Winkel +11
We demonstrate a qubit-readout architecture where the dispersive coupling is entirely mediated by a kinetic inductance. This allows us to engineer the dispersive shift of the reado…
