Cryogenic rf-to-microwave transducer based on a dc-biased electromechanical system
Himanshu Patange, Kyrylo Gerashchenko, Rémi Rousseau +5
We report a two-stage, heterodyne rf-to-microwave transducer that combines a tunable electrostatic pre-amplifier with a superconducting electromechanical cavity. A metalized Si…

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…
