    "abstract": "We propose a tunable on-chip micromaser using a superconducting quantum\ncircuit (SQC). By taking advantage of externally controllable state\ntransitions, a state population inversion can be achieved and preserved for the\ntwo working levels of the SQC and, when needed, the SQC can generate a single\nphoton. We can regularly repeat these processes in each cycle when the\npreviously generated photon in the cavity is decaying, so that a periodic\nsequence of single photons can be produced persistently. This provides a\ncontrollable way for implementing a persistent single-photon source on a\nmicroelectronic chip.",
