Abstract

We study the effects of a parametric frequency converter (PFC) in a two-mode cavity system where one of the cavity modes is coupled with yttrium iron garnet (YIG). The PFC acts as a nonlinear source for enhancing quantum correlations, which strongly depend on the parametric coupling and the associated phase factor. It is fascinating that the perfect transfer of entanglement and steering of various mode pairs can be achieved by adjusting the system’s parameters, such as cavity-magnon coupling, gain, and the phase of the PFC. In addition, the generated entanglements in the present system are more robust against thermal effects, particularly with the inclusion of the PFC, compared to the bare-cavity case. Another intriguing finding is that phonon-cavity one-way steering appears only when magnon-cavity one-way steering completely vanishes. Our protocol for these transferring processes suggests a different approach to the processing and storage of quantum information.

Description We study the enhancement of quantum correlation and perfect transfer of entanglement of indirectly coupled modes via a parametric frequency converter (PFC) in a two-mode magnomechanical system. It is fascinating that the perfect transfer of entanglement and steering of various mode pairs can be achieved by adjusting the system’s parameters, such as cavity-magnon coupling, gain, and the phase of the PFC.

通过参数频率转换器实现纠缠和量子转向的完美转移

本文研究了在双模腔系统中，其中一个腔模式与钇铁石榴石（YIG）耦合的参数化变频器（PFC）的影响。PFC是增强量子相关性的非线性源，量子相关性强烈依赖于参数耦合和相关相位因子。令人着迷的是，通过调整系统的参数，如腔-磁振子耦合、增益和PFC的相位，可以实现纠缠的完美转移和各种模式对的转向。此外，与裸腔情况相比，目前系统中产生的纠缠对热效应更强，特别是在包含PFC的情况下。另一个有趣的发现是，只有当磁振子腔单向转向完全消失时，声子腔单向转向才会出现。我们对这些传输过程的协议提出了一种处理和存储量子信息的不同方法。在双模磁力系统中，通过参数化变频器（PFC）研究了间接耦合模式的量子相关增强和纠缠的完美转移。通过调整系统参数，如腔-磁振子耦合、增益和PFC相位，可以实现纠缠的完美转移和各种模式对的转向。
