“…With an overview at figures 2-4, one may find that the blockade effect of the photon is much stronger than magnon, considering our chosen parameters. As a possible reason for stronger photon blockade comparing to magnon blockade, we may refer to the obtained Kerr-like nonlinearity in effective Hamiltonian (7) resulting from optomechanical interaction which has been previously reported, too [78][79][80]. In addition, the plots indicate that, the magnon and photon blockades possess opposite behavior.…”

Magnon and photon blockade implementation and manipulation have significant practical applications in quantum information processing and quantum metrology due to their tight relations to single-photon and -magnon source devices. In this paper, we propose an experimentally feasible hybrid scheme for the dynamical description of the tripartite interacting system consisting of magnon and phonon modes with photons in an optomechanical system, from which we aim to explore the quantum statistics, as well as the magnon and photon blockade phenomenon. To achieve the purpose, the dissipative solution of the system is obtained with the help of the Lindblad master equation. Via employing the equal-time second-order correlation function and using the steady state solution of the system, the statistics and blockade effects of magnon and photon are analyzed and also their dependence on the parameters involved in the system are discussed. Utilizing feasible parameters, our simulations illustrate that, sub-Poissonian behavior and therefore, blockade of magnon and photon are simultaneously achieved. More importantly, the mentioned blockade effects can be obtained in a range of parameters (and not with specific) which makes our proposal easy to access, experimentally. Considering the above realizations, the introduced scheme opens up a pathway to design single-magnon and - photon generators, which are of crucial importance in advanced quantum science and technologies.

“…Up to now, the controllable single-photon states have been extensively studied by using the mechanisms of conventional PB and unconventional PB. The former mechanism requires a strong optical nonlinearity with large enough energy-spectrum anharmonicity in the systems, ranging from cavity quantum electrodynamics (QED) [8][9][10][11][12][13][14][15][16] to circuit QED [17][18][19][20][21], Kerrtype nonlinear systems [7,[22][23][24][25][26][27][28], and optomechanical resonators [29][30][31][32][33][34][35][36]. The latter mechanism relies on the destructive quantum interference by constructing different quantum transition pathways [37][38][39][40][41][42][43].…”

Single photons and single-photon pairs, inherently nonclassical in their nature, are fundamental elements of quantum sciences and technologies. Here, we propose to realize the nonclassical correlated deterministic photon pairs at the single-photon level for a single atom trapped in bimodal cavities. It is shown that the photon emissions for bimodal cavities exhibit a high single photon purity and relatively large intracavity photon numbers, which are ascribed to the combination of optical Stark shift enhanced energy-spectrum anharmonicity and quantum interference suppressed two-photon excitation. Our scheme generates photon-photon pairs with strong photon blockade for cavity modes via constructing a highly tunable cavity-enhanced deterministic parametric downconversion process. Furthermore, we show that the cross-correlation function between the two cavity modes vastly violates the Cauchy-Schwarz inequality of the classical boundary, which unambiguously demonstrates the nonclassicality of the single-photon pairs. Our result reveals a prominent strategy to generate the high-quality two-mode single-photon sources with strong nonclassical correlation, which could provide versatile applications in distribution of quantum networks, long distance quantum communication, and fundamental tests of quantum physics.

“…[3][4][5] There are two general ideas regarding PB effects: (i) conventional PB (CPB), which originates in the anharmonicity of the energy spectrum, [6] and (ii) unconventional PB (UPB), which results from the destructive quantum interference between the different possible transition paths. [7] On the one hand, the CPB effect, which requires some kind of large nonlinearity, has been researched in various quantum systems, such as Kerr-type nonlinear cavities [8] and optomechanical systems. [9,10] The UPB effect, on the other hand, usually requires a large coupling strength between the two components that structure the different transition paths.…”

We study the single-photon blockade (1PB), two-photon blockade (2PB), and photon-induced tunneling (PIT) effects in a cavity–atom optomechanical system in which a two-level atom is coupled to a single-model cavity field via a two-photon interaction. By analyzing the eigenenergy spectrum of the system, we obtain a perfect 1PB with a high occupancy probability of single-photon excitation, which means that a high-quality and efficient single-photon source can be generated. However, PIT often occurs in many cases when we consider 2PB in analogy to 1PB. In addition, we find that a 2PB region will present in the optomechanical system, which can be proved by calculating the correlation function of the model analytically.
