Coherent Control of Photon Correlations in Trapped Ion Crystals

Popis výsledku v původním jazyce

While the spontaneous emission from independent emitters provides spatially uncorrelated photons a typical manifestation of quantum randomness, the interference of the coherent scattering leads to a well-defined intensity pattern a feature described by linear optics. We here demonstrate experimentally how the interplay between the two mechanisms in large systems of quantum emitters leads to spatial variations of photon correlations. The implementation with trapped ion crystals in free space allows us to observe the anticorrelation between photon rates and variance of the photon number distributions in chains of up to 18 ions. For smaller crystals of four ions, the transition from antibunching to bunching and super-Poissonian statistics of the scattered light is reported. For higher numbers of scatterers, the photon statistics still display a strong deviation from the fully incoherent scattering case. Our results illustrate how the interference of coherent scattering, combined with spontaneous emission, provides a control mechanism for the light statistics.
