“…In particular, the coupling between magnons and optical photons, namely the optomagnonic interaction [19][20][21][22][23], is indispensable for building a magnonic quantum network [37], where the transmission of the information between remote quantum nodes is realized by optical photons. Such an optomagnonic interaction has been exploited in many proposals to cool magnons [38], prepare magnon Fock [39], cat [40], path-entangled [41] states and magnon-photon entangled states [37,42], and realize magnon laser [43,44], high-order sideband generation [45], chaos-order transition [46], frequency combs [47,48], photon blockade [49], polarization-state engineering [50], etc. The typical optomagnomic system, as depicted in Figure 1a, consists of a YIG sphere, which supports both a magnetostatic mode (i.e., the magnon mode) and optical whispering gallery modes (WGMs).…”

A protocol for realizing discrete-variable quantum teleportation in an optomagnonic system is provided. Using optical pulses, an arbitrary photonic qubit state encoded in orthogonal polarizations is transferred onto the joint state of a pair of magnonic oscillators in two macroscopic yttrium-iron-garnet (YIG) spheres that are placed in an optical interferometer. We further show that optomagnonic entanglement swapping can be realized in an extended dual-interferometer configuration with a joint Bell-state detection. Consequently, magnon Bell states are prepared. We analyze the effect of the residual thermal occupation of the magnon modes on the fidelity in both the teleportation and entanglement swapping protocols. The work may find applications in the study of macroscopic quantum states, quantum information processing, and hybrid quantum networks based on magnonics.

“…Dynamical backaction magnomechanics and mechanical bistability have also been observed in cavity magnomechanics [35,36]. Recent proposals have been put forward for achieving magnon entanglement, magnon squeezing, magnon-mediated microwave photon entanglement, magnon blockade, magnon cat states [37][38][39][40][41][42][43][44][45][46]. In addition, magnon-based hybrid systems can also exhibit rich nonlinear phenomena, optomagnonic frequency combs [47], magnonic frequency combs in cavity magnomechanics [48], and magnon-induced high-order sideband generation [49].…”

In this paper, we propose a scheme for measurement-based control of hybrid Einstein–Podolsky–Rosen (EPR) entanglement and steering between distant macroscopic mechanical oscillator and yttrium iron garnet (YIG) sphere in a system of an electromechanical cavity unidirectionally coupled to an electromagnonical cavity. We reveal that when the output of the electromagnonical cavity is continuously monitored by homodyne detection, not only the phonon–magnon entanglement and steering but also the purities of the phononic, magnonic and phonon–magnon states are considerably enhanced. We also find that the measurement can effectively retrieve the magnon-to-phonon steering, which is not yet obtained in the absence of the measurement. We show that unconditional phonon–magnon entanglement and steering can be achieved by introducing indirect feedback to drive the magnon and mechanical subsystems. The long-distance macroscopic hybrid entanglement and steering can be useful for, e.g., fundamental tests for quantum mechanics and quantum networks.

“…The cavity magnomechanical system provides a platform for studying magnon blockade due to the consideration of the interaction between magnons and photons, as well as the interaction between magnons and mechanical oscillators. The study of magnon blockade based on cavity magnomechanical systems have recently attracted the research interest of many scholars [48,[53][54][55].…”

Magnon blockade is one of the eﬀective methods for realizing single magnon sources which have great potential application in quantum information processing and quantum computing. To enhance single-magnon blockade eﬀect, we introduce a two-magnon driving to the magnomechanical system, which is used to form the multipath destructive interference. Our result shows that both the conventional magnon blockade (CMB) and unconventional magnon blockade (UMB) can be achieved due to nonlinear term of the magnon-mechanical oscillator and magnetic parametric ampliﬁcation term(MPA) induced by two-magnon driving. By setting certain parameters of MPA, we combine the eﬀect of CMB and UMB. As a result, the single-magnon blockade eﬀect is enhanced, and the disadvantage of rapid oscillations of the time-delay second-order correlation function g(2)(τ) with UMB is overcome, which makes high time resolution not necessary in the detection of second-order correlation function.
