“…However, these schemes are also restricted by the cavity decay rate since the transformed mechanical mode cannot be cooled to the ground state in the unresolved sideband regime due to the Stokes heating caused by counter‐rotating term. [ 56–63 ] Therefore the mechanical mode in the original picture cannot be strongly squeezed when the cavity is highly dissipative.…”

In the conventional scheme of generating strong mechanical squeezing by the joint effect between mechanical parametric amplification and sideband cooling, the resolved sideband condition is required so as to overcome the quantum backaction heating. In the unresolved sideband regime, to suppress the quantum backaction, a (2) nonlinear medium is introduced to the cavity. The result shows that the quantum backaction heating effect caused by unwanted counter-rotating term can be completely removed. Hence, the strong mechanical squeezing can be obtained even for the system far from the resolved-sideband regime. IntroductionOptomechanical system with the coupling between a cavity field and a macroscopic mechanical oscillator provides us a perfect platform for testing the quantum properties of macroscopic objects, such as macroscopic entanglement, [1][2][3][4][5][6][7][8] macroscopic steering, [9][10][11] macroscopic superposition, [12][13][14] macroscopic state transfer, [15,16] and macroscopic mechanical squeezing. [17][18][19][20][21][22][23] Meanwhile, due to the connection of mechanical motion and cavity field, optomechanical system can be used for high-precision measurements, for instance ultrasensitive force detection, [24][25][26] angular velocity detection, [27,28] small quantities of adsorbed mass detection, [29][30][31] and gravitational wave detection. [32][33][34] In the field of high-precision measurements, optomechanical squeezing, that is, optical squeezing [35][36][37][38] or mechanical squeezing [39][40][41] can effectively improve the precision detection; therefore realizing the squeezing of mechanical mode in optomechanical system is significant for its potential applications.The basic method of generating mechanical squeezing is to introduce a parametric amplification to mechanical oscillator which can be obtained directly by two-phonon driving, [42,43] or indirectly by induced methods such as modulating the frequency of the mechanical oscillator [44] or the amplitude of driving field, [45] driving the cavity with two-tone fields, [46,47] employing the non-Marokovian bath of mechanical mode, [48] etc.Generally speaking, the stationary squeezing is restricted by 3 dB because of the instability caused by the parametric

“…Figure 1 shows the schematics of intracavity squeezing in an OPA-assisted Fabry-Pérot cavity [46,47]. Previous researches on such squeezed quantum systems have usually focused on enhanced mechanical cooling [48][49][50][51] or squeezing [52][53][54] and enhanced light-matter coupling [55][56][57]. When light pressure couples to a movable mirror, coherent states are transformed into squeezed states of light [58], and this type of squeezing, referred to as ponderomotive squeezing [59], can be only used to evade back-action and thus it is less extensive than externally injecting a squeezed light [60] or generating intracavity squeezing via an OPA [46].…”

We investigate quantum-squeezing-enhanced weak-force sensing via a nonlinear optomechanical resonator containing a movable mechanical mirror and an optical parametric amplifier (OPA). Herein, we determined that tuning the OPA parameters can considerably suppress quantum noise and substantially enhance force sensitivity, enabling the device to extensively surpass the standard quantum limit. This indicates that under realistic experimental conditions, we can achieve ultrahighprecision quantum force sensing by harnessing nonlinear optomechanical devices. * These authors contributed equally to this work. †

Optomechanical couplings involve both beam-splitter and two-mode-squeezing types of interactions. While the former underlies the utility of many applications, the latter creates unwanted excitations and is usually detrimental. In this work, we propose a simple but powerful method based on cavity parametric driving to suppress the unwanted excitation that does not require working with a deeply sideband-resolved cavity. Our approach is based on a simple observation: as both the optomechanical two-mode-squeezing interaction and the cavity parametric drive induce squeezing transformations of the relevant photonic bath modes, they can be made to cancel one another. We illustrate how our method can cool a mechanical oscillator below the quantum back-action limit, and significantly suppress the output noise of a sideband-unresolved optomechanical transducer.
