“…Photon blockade in the optomechanical system was first studied in 2011 by Rabl [26] and Girvin [38] . Later, it was widely studied in various optomechanical structures, including non-reciprocal systems [28] , parity-time-symmetric cavity systems [33] , [39] , and high-order coupling optomechanics [27] , [40] .…”

“…These types of systems possess a broad range of important applications, which include the ability to generate different bipartite [24] and tripartite [25] entanglements and sensitive measurements of mechanical motion [26][27][28], photon blockade [29][30][31], phonon blockade [32,33] and optical squeezing, which were investigated from both theoretical and experimental points of view [34][35][36]. An extension of such systems is an optomechanical system with second-order, i.e., quadratic coupling, wherein nonlinear interaction between photons and phonons provides conditions for performing many interesting phenomena, especially squeezing [37][38][39], photon blockade [40][41][42], which was first presented by Rabl et al [43,44], and phonon blockade [45][46][47][48][49]. Now, we continue with referring to the literature dealing with linear and nonlinear optomechanical cavities with more details on the squeezing and blockade that have been of interest in these systems.…”

In this paper, we present a theoretical scheme for the generation and manipulation of bipartite atom–atom entanglement in a dissipative optomechanical system containing two atoms in the presence of linear and nonlinear (quadratic) couplings. To achieve the goal of paper, we first obtain the interaction Hamiltonian in the interaction picture, and then, by considering some resonance conditions and applying the rotating wave approximation, the effective Hamiltonian, which is independent of time, is derived. In the continuation, the system solution was obtained via solving the Lindblad master equation, which includes atomic, optical and mechanical dissipation effects. Finally, bipartite atom–atom entanglement is quantitatively discussed, by evaluating the negativity, which is a well-known measure of entanglement. Our numerical simulations show that a significant degree of entanglement can be reached via adjusting the system parameters. It is noticeable that the optical and mechanical decay rates play an important role in the quasi-stability and even stability of the obtained atom–atom entanglement.

“…In close analogy to Coulomb blockade [14] and photon blockade [15][16][17][18][19][20][21][22], PB is a pure quantum effect, which plays an important role in unveiling the quantum behavior of a device. The initial single-phonon blockade (1PB) was achieved in a nanomechanical resonator, which is coupled to a superconducting quantum two-level system for inducing self-interactions of phonons.…”

Quantum nonreciprocal devices have received extensive attention in recent years because they can be used to realize unidirectional quantum routing and noise isolation. In this work, we show that the shift of resonance frequencies of propagating phonons induced by spin-orbit interactions (SOI) of phonons in a rotating acoustic ring cavity can be used to realize nonreciprocal phonon blockade. When driving the cavity from different directions, nonreciprocal single-, two-phonon blockade and phonon-induced tunneling can take place by varying the parameters of the system to an appropriate value. To realize phonon blockade, the sublevels of the lower orbit branch of the ground state of silicon-vacancy (SiV) color centers in the diamond membrane are employed to induce self-interactions of phonons in the cavity. This work provides a way to achieve acoustic nonreciprocal devices, such as directional acoustic switches and quantum noise isolation, which may help acoustic information network processing.
