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…

On-chip stencil lithography for superconducting qubits
Roudy Hanna, Sören Ihssen, Simon Geisert +22
Improvements in circuit design and more recently in materials and surface cleaning have contributed to a rapid development of coherent superconducting qubits. However, organic resi…

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…
