Abstract:The preparation of Fock states is important for quantum information storage and processing. Here we present a two‐step protocol with topological protection for multi‐photon Fock states synthesizing in a circuit QED architecture. Due to photon number‐dependent vacuum Rabi splitting, the dynamics of the Jaynes‐Cummings ladder in the resonant regime can be equivalent to a spin‐1/2 chain while a multi‐frequency microwave pulse is applied. Based on the topologically assisted quantum state transfer technique, multi‐… Show more
