Topology-dependent quantum dynamics and entanglement-dependent topological pumping in superconducting qubit chains

10 Jan 2019 Mei Feng Chen Gang Tian Lin Zhu Shi-Liang Jia Suotang

We propose a protocol using a tunable Xmon qubit chain to construct generalized Su-Schrieffer-Heeger (SSH) models that support various topological phases. We study the time evolution of a single-excitation quantum state in a SSH-type qubit chain and find that such dynamics is linked to topological winding number... (read more)
