A macroscopic object passively cooled into its quantum ground state of motion: beyond single-mode cooling
D. Cattiaux, I. Golokolenov, S. Kumar +8
The building blocks of Nature, namely atoms and elementary particles, are described by quantum mechanics. This fundamental theory is the ground on which physicists have built their…
Geometrical Nonlinearity of Circular Plates and Membranes: an Alternative Method
D. Cattiaux, S. Kumar, X. Zhou +2
We apply the well-established theoretical method developed for geometrical nonlinearities of micro/nano-mechanical clamped beams to circular drums. The calculation is performed und…
On-chip thermometry for microwave optomechanics implemented in a nuclear demagnetization cryostat
X. Zhou, D. Cattiaux, R. R. Gazizulin +7
We report on microwave optomechanics measurements performed on a nuclear adiabatic demagnetization cryostat, whose temperature is determined by accurate thermometry from below 500$…
Surface-induced near-field scaling in the Knudsen layer of a rarefied gas
R. R. Gazizulin, O. Maillet, X. Zhou +3
We report on experiments performed within the Knudsen boundary layer of a low-pressure gas. The non-invasive probe we use is a suspended nano-electro-mechanical string (NEMS), whic…
Magnetic resonance with squeezed microwaves
A. Bienfait, P. Campagne-Ibarcq, A. Holm-Kiilerich +9
Vacuum fluctuations of the electromagnetic field set a fundamental limit to the sensitivity of a variety of measurements, including magnetic resonance spectroscopy. We report the u…
Reaching the quantum limit of sensitivity in electron spin resonance
A. Bienfait, J. J. Pla, Y. Kubo +12
We report pulsed electron-spin resonance (ESR) measurements on an ensemble of Bismuth donors in Silicon cooled at 10mK in a dilution refrigerator. Using a Josephson parametric micr…
Multiplexed Readout of Transmon Qubits with Josephson Bifurcation Amplifiers
V. Schmitt, X. Zhou, K. Juliusson +4
Achieving individual qubit readout is a major challenge in the development of scalable superconducting quantum processors. We have implemented the multiplexed readout of a four tra…
