Ground-state cooling of a micromechanical oscillator: Comparing cold damping and cavity-assisted cooling schemes
We provide a general framework to describe cooling of a micromechanical oscillator to its quantum ground state by means of radiation-pressure coupling with a driven optical cavity. We apply it to two…

Microwave quantum illumination using a digital receiver
TLDR
This work generates entangled fields to illuminate a room-temperature object at a distance of 1 m in a free-space detection setup and implements a digital phase-conjugate receiver based on linear quadrature measurements that outperforms a symmetric classical noise radar in the same conditions, despite the entanglement-breaking signal path.

Microwave quantum illumination.
TLDR
The error probability of this microwave quantum-illumination system, or quantum radar, is shown to be superior to that of any classical microwave radar of equal transmitted energy.

Optomechanical entanglement between a movable mirror and a cavity field
TLDR
An experimental scheme to create and probe optomechanical entanglement between a light field and a mechanical oscillator is proposed using a bright laser field that resonates inside a cavity and couples to the position and momentum of a moving (micro)mirror.

Entangling optical and microwave cavity modes by means of a nanomechanical resonator
We propose a scheme that is able to generate stationary continuous-variable entanglement between an optical and a microwave cavity mode by means of their common interaction with a nanomechanical…

Robust entanglement of a micromechanical resonator with output optical fields
We perform an analysis of the optomechanical entanglement between the experimentally detectable output field of an optical cavity and a vibrating cavity end-mirror. We show that by a proper choice of…

Phase-noise measurement in a cavity with a movable mirror undergoing quantum Brownian motion
We study the dynamics of an optical mode in a cavity with a movable mirror subject to quantum Brownian motion. We study the phase noise power spectrum of the output light, and we describe the mirror…

Characterizing the entanglement of bipartite quantum systems
We derive a separability criterion for bipartite quantum systems which generalizes the already known criteria. It is based on observables having generic commutation relations. We then discuss in…

Reversible optical-to-microwave quantum interface.
TLDR
It is shown that, by employing state-of-the-art optoelectromechanical devices, one can realize an effective source of (bright) two-mode squeezing with an optical idler and a microwave signal, which can be used for high-fidelity transfer of quantum states between optical and microwave fields by means of continuous variable teleportation.

Optomechanically induced transparency in a membrane-in-the-middle setup at room temperature
Summary form only given. In cavity optomechanics one can manipulate the dynamics of a nanomechanical resonator with light, and at the same time one can control light by tayloring its interaction with…
