A scanning resonator for probing quantum coherent devices
Jared Gibson, Zhanzhi Jiang, Angela Kou
Superconducting resonators with high quality factors are extremely sensitive detectors of the complex impedance of materials and devices coupled to them. This capability has been u…

Fluxonium as a control qubit for bosonic quantum information
Ke Nie, J. Nofear Bradford, Supriya Mandal +3
Bosonic codes in superconducting resonators are a hardware-efficient avenue for quantum error correction and benefit from favorable error hierarchies provided by long-lived cavitie…

Readout-induced leakage of the fluxonium qubit
Aayam Bista, Matthew Thibodeau, Ke Nie +3
Dispersive readout is widely used to perform high-fidelity measurement of superconducting qubits. Much work has been focused on the qubit readout fidelity, which depends on the ach…
