论文摘要
单量子水平的手性耦合有望成为量子信息处理的显着潜力。在这里，我们建议在铁磁球中获得镁模式之间的手性相互作用，以及由一维耦合式腔阵列介导的超导量子量子。当量子耦合到阵列的两个晶格位点，并且每个量子位均用可调阶段编码时，我们可以通过量子干扰效应获得方向性的Qubit-Magnon相互作用。这项工作开辟了一条新的构建手性设备的途径，预计将成为量子宏伟网络中的一个基础。
Chiral coupling at the single-quantum level promises to be a remarkable potential for quantum information processing. Here we propose to achieve a chiral interaction between a magnon mode in a ferromagnetic sphere and a superconducting qubit mediated by a one-dimensional coupled-cavity array. When the qubit is coupled to two lattice sites of the array and each one is encoded with a tunable phase, we can acquire a directional qubit-magnon interaction via the quantum interference effect. This work opens up a new route to construct chiral devices, which are expected to become a building block in quantum magnonic networks.
