Squeezer-based pulsed optomechanical interface

Abstract

We prove feasibility of high-fidelity pulsed optomechanical interface based on all-optical presqueezing of non-Gaussian quantum states of light before they enter the optomechanical system. We demonstrate that feasible presqueezing of optical states effectively increases the low noise transfer of them to mechanical oscillator. It allows one to surpass the limit necessary to transfer highly nonclassical states with negative Wigner function. In particular, we verify that with this help single photon states of light can be efficiently turned to single phonon states of mechanical oscillator, keeping the negativity of the Wigner function. It opens the possibility to merge quantum optomechanics with the recent methods of quantum optics.Comment: 10 pages, 3 figures, published versio

Robust optomechanical state transfer under composite phase driving

“…In cavity optomechanical systems, the motion of the mechanical oscillator can be cooled by tuning the laser that pumps the cavity [19][20][21][22], leading to experiments where a nano-oscillator is cooled to its quantum-mechanical ground state [23][24][25]. Previous works propose diverse techniques to enhance optomechanical cooling, for example, by dynamically modifying the damping [26], using squeezed light [27][28][29][30], feedbackcontrolled light [31,32], or considering the effects of non-Markovian evolution [33]. These developments show that optomechanical effects allow control over quantum optical and mechanical states leading to exciting proposals to use these systems as transducers [34][35][36][37][38][39].…”

Quantum optomechanical transducer with ultrashort pulses

“…To be fully compatible with modern hybrid quantum optics [22][23][24][25], pulsed versions of quantum optomechanics have been initiated in two regimes: exponentially modulated pulses with duration significantly exceeding the mechanical period [26] and high-intensity pulses which are very short compared to the mechanical period [27]. The former has been used to demonstrate Gaussian entanglement between microwave field and mechanical oscillator [28], quantum state transfer [29,30], non-classical photon-phonon correlations [31,32], entanglement between distant mechanical oscillators [33], and also motivated other theoretical ideas [34][35][36]. Likewise, the latter approach, also known as stroboscopic, has stimulated a number of experimental [37] and theoretical [38,39] works.…”

Extracting work from quantum states of radiation

“…These experiments can be extended to prepare various quantum states of mechanical system [38][39][40][41][42][43][44][45]. To reach a high quality of transfer for any state of light to mechanical systems, universal interfaces have been proposed as well [46][47][48][49]. Remaining main experimental challenge is therefore the direct coupling of the mechanical system at quantum level to a classical thermodynamic system.…”
