论文摘要
我们提出了一种理论方法，将使用铁或铁磁性纳米颗粒作为微波纳米磁性腔，将微波磁场集中到深层下波长体积$ \ sim 10^{ - 13} $ mm $ $ $^3 $中。我们表明，这种纳米腔中的田地可以有效地将其与位于纳米颗粒表面接近的孤立自旋发射器（自旋量子）（旋转量子），到达单个镁旋转强耦合方案，并介导孤立的自旋发射器之间的有效远距离量子态转移。因此，纳米磁腔铺平了迈向基于镁基的量子网络和镁介导的量子门的道路。
We present a theoretical approach to use ferro- or ferrimagnetic nanoparticles as microwave nanomagnonic cavities to concentrate microwave magnetic fields into deeply subwavelength volumes $\sim 10^{-13}$ mm$^3$. We show that the field in such nanocavities can efficiently couple to isolated spin emitters (spin qubits) positioned close to the nanoparticle surface reaching the single magnon-spin strong-coupling regime and mediate efficient long-range quantum state transfer between isolated spin emitters. Nanomagnonic cavities thus pave the way towards magnon-based quantum networks and magnon-mediated quantum gates.
