We measured first [1] and second order correlation functions of the light spontaneously emitted from a trapped, cold two-ion crystal for various detector positions in the temporal regime. Strikingly, the g(2)(x→, τ) signal shows bunching or antibunching for different observer positions [2]. Position sensitive Micro Channel Plate detectors developed for applications in fluorescence lifetime microscopy combining a high spatial resolution with temporal resolution. By using two detectors in correlation mode, it is possible to implement intensity interferometry with the light of a two-ion crystals. The spatial modulation of g(2)(x1→, x2→, τ) was predicted in [3] and can now be measured by recording the corresponding two photon events for any time difference Δ T and corresponding positions x1→ and x2→. After the event stream is recorded, the correlations for arbitrary geometries can be reconstructed. [1] S. Wolf et al., Phys. Rev. Lett. 116, 183002 (2016) [2] S. Wolf et al., in preparation [3] C.
