FerBo: a noise resilient qubit hybridizing Andreev and fluxonium states
J. J. Caceres, D. Sanz Marco, J. Ortuzar +6
We propose a novel superconducting quantum circuit that should be robust against both relaxation and dephasing over a wide and experimentally accessible parameter range. The circui…
Superconducting Parallel-Plate Resonators for the Detection of Single Electron Spins
André Pscherer, Jannes Liersch, Patrick Abgrall +7
We introduce a multilayer superconducting microwave resonator with sub-Ohm impedance optimized for high coupling strength to single electron spins. The design minimizes the magneti…
Probing the quantum motion of a macroscopic mechanical oscillator with a radio-frequency superconducting qubit
Kyrylo Gerashchenko, Rémi Rousseau, Léo Balembois +11
Long-lived mechanical resonators like drums oscillating at MHz frequencies and operating in the quantum regime are a powerful platform for quantum technologies and tests of fundame…
Hyperinductance based on stacked Josephson junctions
Paul Manset, José Palomo, Aurélien Schmitt +8
Superinductances are superconducting circuit elements that combine a large inductance with a low parasitic capacitance to ground, resulting in a characteristic impedance exceeding…
