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…
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…
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…
FPGA-based feedback control of quantum optics experiments with the open source software package PyRPL
Leonhard Neuhaus, Michaël Croquette, Rémi Metzdorff +8
We present PyRPL, an open source software package that allows the implementation of automatic digital feedback controllers for quantum optics experiments on commercially available,…
High-sensitivity AC-charge detection with a MHz-frequency fluxonium qubit
B. -L. Najera-Santos, R. Rousseau, K. Gerashchenko +15
Owing to their strong dipole moment and long coherence times, superconducting qubits have demonstrated remarkable success in hybrid quantum circuits. However, most qubit architectu…
Laser cooling of a Planck mass object close to the quantum ground state
Leonhard Neuhaus, Remi Metzdorff, Salim Zerkani +13
Quantum mechanics has so far not been tested for mechanical objects at the scale of the Planck mass . We present an experiment where a 1 m…
Detecting itinerant microwave photons with engineered non-linear dissipation
Raphaël Lescanne, Samuel Deléglise, Emanuele Albertinale +6
Single photon detection is a key resource for sensing at the quantum limit and the enabling technology for measurement based quantum computing. Photon detection at optical frequenc…
Probing a two-level system bath via the frequency shift of an off-resonantly-driven cavity
Thibault Capelle, Emmanuel Flurin, Edouard Ivanov +8
Although the main loss channel of planar microwave superconducting resonators has been identified to be related to an external coupling to a two-level system (TLS) bath, the behavi…
High-finesse Fabry-Perot cavities with bidimensional SiN photonic-crystal slabs
Xu Chen, Clément Chardin, Kevin Makles +9
Light scattering by a two-dimensional photonic crystal slab (PCS) can result in dramatic interference effects associated with Fano resonances. Such devices offer appealing alternat…
