外文摘要：High-order quantum coherence reveals the statistical correlation of quantum particles.Manipulation of quan-tum coherence of light in the temporal domain enables the production of the single-photon source,which has become one of the most important quantum resources.High-order quantum coherence in the spatial domain plays a crucial role in a variety of applications,such as quantum imaging,holography,and microscopy.However,the active control of second-order spatial quantum coherence remains a challenging task.Here we predict theoreti-cally and demonstrate experimentally the first active manipulation of second-order spatial quantum coherence,which exhibits the capability of switching between bunching and anti-bunching,by mapping the entanglement of spatially structured photons.We also show that signal processing based on quantum coherence exhibits robust resistance to intensity disturbance.Our findings not only enhance existing applications but also pave the way for broader utilization of higher-order spatial quantum coherence.
