• Abstract summary: We present the experimental characterization of both coherent and statistical properties of light emitted from ensembles of trapped ions. We show how super-Poissonian quantum statistics non-trivially arises purely from the finite number of indistinguishable single-photon emitters. The achieved new optical emission regime provides a new perspective on the emergence of optical coherence at the atomic scale.

• Abstract: The optical interference constitutes a paramount resource in modern physics. At the scale of individual atoms and photons, it is a diverse concept that causes different coherent phenomena. We present the experimental characterization of both coherent and statistical properties of light emitted from ensembles of trapped ions increasing with a number of contributing phase-incoherent independent atomic particles ranging from a single to up to several hundreds. It conclusively demonstrates how super-Poissonian quantum statistics non-trivially arises purely from the finite number of indistinguishable single-photon emitters in the limit of a single detection mode. The achieved new optical emission regime in which these independent atoms contribute coherently to the super-Poissonian statistics provides a new perspective on the emergence of optical coherence at the atomic scale and constitutes a unique toolbox for its generation and control at the most microscopic level.

  We show that the single-photon nonlinearity vanishes with the number of emitters. The mechanism behind this behavior is the quantum Zeno effect, manifested in the slowdown of the photon-controlled dynamics.

  We study the single-photon collective dynamics in a waveguide system consisting of the photon channel with a finite bandwidth and an ensemble of quantum emitters. Our findings lead to the prediction that single-photon collective emissions can be strongly suppressed if the number of excited emitters is much less than the total number of emitters in the system.

  We propose a scheme for producing bursts of polarised single photons by coupling a generalised atomic emitter to an optical cavity. In connection with two re-preparation methods, simulations predict 10-photon bursts coincidence count rates on the order of 1 kHz. This paves the way for novel n-photon experiments with atom-cavity sources.

  We consider an ensemble of Alkali atoms that are continuously optically pumped and probed. Due to the collective scattering of photons at large optical depth, the steady state of atoms does not correspond to an uncorrelated tensor-product state. We find and characterize regimes of Raman lasing, akin to the model of a superradiant laser.

  Hong-Ou-Mandel (HOM) effect can lead to a perfect suppression of two-particle coincidences between the output ports of a balanced beam splitter. In this work, we demonstrate experimentally that the two-particle coincidence statistics of two bosons can instead be seamlessly tuned to substantial enhancement. Our findings reveal a new approach to harnessing non-Hermitian settings for the manipulation of multi-particle quantum states.

  We investigate, in a four photon interference experiment in a laser-written waveguide structure, how symmetries control the suppression of many-body output events of a $J_x$ unitary. We show that totally destructive interference does not require mutual indistinguishability between all, but only between symmetrically paired particles.

The scheme can be extended to random number generation by coherent single photons with potential applications in solid-state based quantum communication at room temperature.
