论文摘要
我们研究了选择性空腔耦合到拓扑链来调整Majorana fermions的连通性的能力。我们展示了如何通过选择性地访问与特定物理位点的轻度相互作用，如何将与非本地主要fermion配对相关的拓扑Qubits（TQS（TQ）（TQ）转移到大部分拓扑链中。特别是，我们介绍了一项全面的DMRG研究，对不同链腔耦合的几何形状中的地面特征并验证了强耦合方案中的分析见解。这种新型的Majorana Fermion相关生成过程带有新的空腔光子特征。此外，通过考虑腔体 - 耦合强度突然淬灭后的时间演化，我们表明，高非平凡问题（Majoraana）相关性的发展使腔中可测量的非经典光子烙印消失了。因此，提供了在任意长度的拓扑链中动态生成TQ非局部相关性的新方法，为混合光子固态系统中可控的远距离纠缠打开了替代途径。
We investigate the ability of selective cavity coupling to a topological chain for tailoring the connectivity of Majorana fermions. We show how topological qubits (TQs), associated with non-local Majorana fermion pairing, can be moved from the edge to the bulk of a topological chain through selective access to light-matter interaction with specific physical sites. In particular, we present a comprehensive DMRG study of ground-state features in different chain-cavity coupling geometries and validate analytical insights in the strong coupling regime. This new kind of Majorana fermion correlation generation process comes with new cavity photon features. Moreover, by considering the time evolution after a sudden quench of the cavity-matter coupling strength, we show that the development of high non-trivial matter (Majorana) correlations leaves off measurable non-classical photon imprints in the cavity. New ways to dynamically generate TQ nonlocal correlations in topological chains of arbitrary length are thus provided, opening alternative routes to controllable long-range entanglement in hybrid photonic solid-state systems.
