The search for experimental demonstration of the quantum behavior of macroscopic
mechanical resonators is a fast growing field of investigation and recent results suggest that …

A pair of conjugate observables, such as the quadrature amplitudes of harmonic motion,
have fundamental fluctuations that are bound by the Heisenberg uncertainty relation …

Nanomechanical oscillators are at the heart of ultrasensitive detectors of force, mass and
motion,,,,. As these detectors progress to even better sensitivity, they will encounter …

We introduce a framework of optomechanical systems that are driven with a mildly amplitude-
modulated light field, but that are not subject to classical feedback or squeezed input light …

The sensitive measurement of electrical signals is at the heart of modern technology.
According to the principles of quantum mechanics, any detector or amplifier necessarily …

Rapid experimental progress has recently allowed the use of light to prepare macroscopic
mechanical objects into nearly pure quantum states. This research field of quantum …

We discuss how large amounts of steady-state quantum squeezing (beyond 3 dB) of a
mechanical resonator can be obtained by driving an optomechanical cavity with two control …

Utilizing the tools of quantum optics to prepare and manipulate quantum states of motion of
a mechanical resonator is currently one of the most promising routes to explore non …

We study theoretically a three-mode optomechanical system where two mechanical
oscillators are independently coupled to a single cavity mode. By optimized two-tone or four …

Quantum squeezing in mechanical systems is not only a key signature of macroscopic
quantum effects, but can also be utilized to advance the metrology of weak forces. Here we …
