Emission of photon multiplets by a dc-biased superconducting circuit
G. C. Ménard, A. Peugeot, C. Padurariu +12
We observe the emission of bunches of photons by a circuit made of a microwave resonator in series with a voltage-biased tunable Josephson junction. The bunches are…
Design of a Cooper pair box electrometer for application to solid-state and astroparticle physics
Leandro Tosi, Denis Vion, Hélène le Sueur
We describe the design and principle of operation of a fast and sensitive electrometer operated at millikelvin temperatures, which aims at replacing conventional semiconducting cha…
Manipulating Fock states of a harmonic oscillator while preserving its linearity
Kristinn Juliusson, Simon Bernon, Xin Zhou +7
We present a new scheme for controlling the quantum state of a harmonic oscillator by coupling it to an anharmonic multilevel system (MLS) with first to second excited state transi…
Lumped Element Kinetic Inductance Detectors for space applications
Alessandro Monfardini, Jochem Baselmans, Alain Benoit +12
Kinetic Inductance Detectors (KID) are now routinely used in ground-based telescopes. Large arrays, deployed in formats up to kilopixels, exhibit state-of-the-art performance at mi…
Quantum coherence engineering in the integer quantum Hall regime
P-A. Huynh, F. Portier, H. le Sueur +6
We present an experiment where the quantum coherence in the edge states of the integer quantum Hall regime is tuned with a decoupling gate. The coherence length is determined by me…
Chargeless heat transport in the fractional quantum Hall regime
C. Altimiras, H. le Sueur, U. Gennser +4
We demonstrate a direct approach to investigate heat transport in the fractional quantum Hall regime. At filling factor of 4/3, we inject power at quantum point contacts and detect…
Strong back-action of a linear circuit on a single electronic quantum channel
F. D. Parmentier, A. Anthore, S. Jezouin +5
What are the quantum laws of electricity in mesoscopic circuits? This very fundamental question has also direct implications for the quantum engineering of nanoelectronic devices.…
Tuning Energy Relaxation along Quantum Hall Channels
C. Altimiras, H. le Sueur, U. Gennser +3
The chiral edge channels in the quantum Hall regime are considered ideal ballistic quantum channels, and have quantum information processing potentialities. Here, we demonstrate ex…
Energy Relaxation in the Integer Quantum Hall Regime
H. le Sueur, C. Altimiras, U. Gennser +3
We investigate the energy exchanges along an electronic quantum channel realized in the integer quantum Hall regime at filling factor . One of the two edge channels is drive…
Non-Equilibrium Edge Channel Spectroscopy in the Integer Quantum Hall Regime
C. Altimiras, H. le Sueur, U. Gennser +3
Heat transport has large potentialities to unveil new physics in mesoscopic systems. A striking illustration is the integer quantum Hall regime, where the robustness of Hall curren…
Plasmon scattering approach to energy exchange and high frequency noise in nu=2 quantum Hall edge channels
Pascal Degiovanni, Charles Grenier, Gwendal Fève +3
Inter-edge channel interactions in the quantum Hall regime at filling factor nu= 2 are analyzed within a plasmon scattering formalism. We derive analytical expressions for energy r…
