摘要:

光学干涉是现代物理学中的一个重要资源。在单个原子和光子的尺度上,这是一个不同的概念,导致不同的相干现象。我们提出的实验表征的相干和统计特性的光从合奏的被困离子增加了一些贡献的相位不相干的独立的原子粒子范围从一个到几百个。它最终证明了超泊松量子统计如何非平凡地纯粹从有限数量的不可区分的单光子发射器在一个单一的检测模式的限制。实现新的光发射制度,其中这些独立的原子有助于相干的超泊松统计提供了一个新的视角出现在原子尺度上的光学相干性,并构成了一个独特的工具箱,其产生和控制在最微观的水平。

英文摘要:

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.
