Beyond linear coupling in microwave optomechanics
D. Cattiaux, X. Zhou, S. Kumar +8
We explore the nonlinear dynamics of a cavity optomechanical system. Our realization consisting of a drumhead nano-electro-mechanical resonator (NEMS) coupled to a microwave cavity…
Sideband cooling of nearly degenerate micromechanical oscillators in a multimode optomechanical system
C. F. Ockeloen-Korppi, M. F. Gely, E. Damskägg +3
Multimode optomechanical systems are an emerging platform for studying fundamental aspects of matter near the quantum ground state and are useful in sensitive sensing and measureme…
Revealing hidden quantum correlations in an electromechanical measurement
C. F. Ockeloen-Korppi, E. Damskägg, G. S. Paraoanu +2
Under a strong quantum measurement, the motion of an oscillator is disturbed by the measurement back-action, as required by the Heisenberg uncertainty principle. When a mechanical…
Interfacing planar superconducting qubits with high overtone bulk acoustic phonons
Mikael Kervinen, Ilkka Rissanen, Mika Sillanpaa
Mechanical resonators are a promising way for interfacing qubits in order to realize hybrid quantum systems that offer great possibilities for applications. Mechanical systems can…
