Optomechanical generation of a mechanical catlike state by phonon subtraction
Itay Shomroni, Liu Qiu, Tobias J. Kippenberg
We propose a scheme to prepare a macroscopic mechanical oscillator in a catlike state, close to a coherent state superposition. The mechanical oscillator, coupled by radiation-pres…

Laser cooling of a nanomechanical oscillator to the zero-point energy
Liu Qiu, Itay Shomroni, Paul Seidler +1
Optomechanical cavities in the well-resolved-sideband regime are ideally suited for the study of a myriad of quantum phenomena with mechanical systems, including backaction-evading…

Two-Tone Optomechanical Instability and Its Fundamental Implications for Backaction-Evading Measurements
Itay Shomroni, Amir Youssefi, Nick Sauerwein +5
While quantum mechanics imposes a fundamental limit on the precision of interferometric measurements of mechanical motion due to measurement backaction, the nonlinear nature of the…
