Trapped ions provide an exceptionally well-controlled quantum system with truly identical particles confined in deep potentials and manipulated with extraordinary precision. Each ion acts as a single-photon emitter allowing us to investigate collective light*matter interactions at the most fundamental level. In the past, we observed interference in both first- and second-order photon correlation functions, revealing spin-textures [1], spatially dependent bunched and antibunched photon statistics [2], superradiance and subradiance as well as measurement induced entanglement [3].
In this talk, I present our new experimental platform which combines, a multisegmented trap for the versatile control of the emitter positions. Furthermore, the setup features high-numerical-aperture detection from opposite directions, enabling efficient exploration of spatiotemporal photon correlations emitted from ion crystals of 50 and more ions. I report the system characterization along recent data and sketch future experiments.
