Nearly quantum-limited microwave amplification via interfering degenerate stimulated emission in a single artificial atom

Nearly quantum-limited microwave amplification via interfering degenerate stimulated emission in a single artificial atom

Abstract Reaching the quantum limit for added noise in amplification processes is an important step toward many quantum technologies. Nearly quantum-limited traveling-wave parametric amplifiers with Josephson junction arrays have been developed and recently even become commercially available. Howeve...
