Chirality-induced one-way quantum steering between two waveguide-mediated ferrimagnetic microspheres

One-way quantum steering is of importance for technologies, such as secure teleportation. In this paper, we study the generation one-way between two distant yttrium iron garnet (YIG) microspheres in chiral waveguide electromagnonics. We consider that magnon mode with Kerr nonlinearity each YIG sphere chirally coupled to left- and right-propagating guided photons waveguide. find modes absent nonchirality but present merely form one way (i.e., steering) when chirality occurs. The maximal achievable obviously improved degree increases. further waveguide's outputs are subjected continuous homodyne detection, can be considerably enhanced asymmetric strong entanglement also achieved by tuning chirality. Our shows explored effectively realize steering. Compared other studies on achieving via controlling intrinsic dissipation, e.g., cavity loss rates, our scheme depends enabled positioning micromagnets continuously adjustable experimentally more feasible.
