论文摘要
虽然设计光子的能量摩孔关系是许多线性，非线性和量子光学现象的关键，但可以通过使用光子浴本身的拓扑结构来实现一组新的轻质属性。在这项工作中，我们研究了基于Su-Schrieffer-Heeger模型的光子类似物的超导量子置量子位的特性。我们探索了与这种波导相连的Qubits的拓扑诱导的特性，从定向量子量子粘结状态的形成到拓扑依赖性的合作辐射效应。在此波导系统中添加Qubits还可以对有限波导系统中形成的拓扑边缘状态进行直接量子控制，例如在构建拓扑保护的量子通信通道中有用。从更广泛的角度来看，我们的工作证明了拓扑波导系统在综合和研究具有异国情调长期量子相关的多体状态的机会。
While designing the energy-momentum relation of photons is key to many linear, non-linear, and quantum optical phenomena, a new set of light-matter properties may be realized by employing the topology of the photonic bath itself. In this work we investigate the properties of superconducting qubits coupled to a metamaterial waveguide based on a photonic analog of the Su-Schrieffer-Heeger model. We explore topologically-induced properties of qubits coupled to such a waveguide, ranging from the formation of directional qubit-photon bound states to topology-dependent cooperative radiation effects. Addition of qubits to this waveguide system also enables direct quantum control over topological edge states that form in finite waveguide systems, useful for instance in constructing a topologically protected quantum communication channel. More broadly, our work demonstrates the opportunity that topological waveguide-QED systems offer in the synthesis and study of many-body states with exotic long-range quantum correlations.
