Single Artificial-Atom Lasing of a Dressed Flux Qubit
Superconducting quantum bits originally developed for quantum computation have properties similar to real atoms. Because they are micro fabricated circuits, their interaction with electromagnetic radiation can be engineered and effects known from quantum optics may be realized.In this work, a unique lasing scheme exploiting only the lowest two levels of a single artificial atom coupled to a high-quality superconducting resonator ...
