[Seminar:C700&Zoom] Non-linear effects in Hybrid Quantum Systems

Non-linear effects in Hybrid Quantum Systems

Bill Munro

NTT Basic Research Laboratories & NTT Research Center for Theoretical Quantum Physics

The hybridization of distinct quantum systems has opened a new regime of physics where we can controllably explore coherent non-linear phenomena with the aim of finding new quantum technologies based on them. Superradiance, a fundamental collective effect where radiation is amplified by the coherence of multiple emitters, is one of the most well-known archetypal examples of such phenomena. Hybrid quantum systems composed of spin ensembles coupled to resonators are a natural test bed to explore such phenomenon and so we use such a system to dynamically observe a superradiant pulse of light being emitted a trillion times faster than the decay of the individual atoms making up the ensemble. We then discuss various applications of this phenomena in quantum systems ranging from quantum batteries to the fast migration of energy and quantum correlations.
