Nonclassical energy squeezing of a macroscopic mechanical oscillator
Xizheng Ma, Jeremie J. Viennot, Shlomi Kotler +2
Optomechanics and electromechanics have made it possible to prepare macroscopic mechanical oscillators in their quantum ground states, in quadrature squeezed states, and in entangl…

Resolving Phonon Fock States in a Multimode Cavity with a Double-Slit Qubit
Lucas R. Sletten, Bradley A. Moores, Jeremie J. Viennot +1
We resolve phonon number states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. Crucial to this resolution is the sharp frequency dependence in t…

Phonon number sensitive electromechanics
Jeremie J. Viennot, Xizheng Ma, Konrad W. Lehnert
We use the strong intrinsic non-linearity of a microwave superconducting qubit with a 4 GHz transition frequency to directly detect and control the energy of a micro-mechanical osc…
