  text: Recent advancements in superconducting circuits have enabled the experimental
    study of collective behavior of precisely controlled intermediate-scale ensembles
    of qubits. In this work, we demonstrate an atomic frequency comb formed by individual
    artificial atoms strongly coupled to a single resonator mode. We observe periodic
    microwave pulses that originate from a single coherent excitation dynamically
    interacting with the multiqubit ensemble. We show that this revival dynamics emerges
    as a consequence of the constructive and periodic rephasing of the five superconducting
    qubits forming the vacuum Rabi split comb. In the future, similar devices could
    be used as a memory with in situ tunable storage time or as an on-chip periodic
    pulse generator with nonclassical photon statistics.
