Query: Multiphoton Quantum van Cittert-Zernike Theorem   Recent progress on quantum state engineering has enabled the preparation of
quantum photonic systems comprising multiple interacting particles.
Interestingly, multiphoton quantum systems can host many complex forms of
interference and scattering processes that are essential to perform operations
that are intractable on classical systems. However, the control of quantum
multiphoton systems represents one of the most important challenges in the
field of quantum optics. Here, we unveil new mechanisms to control nonclassical
coherence of multiphoton systems, these interactions are described through the
quantum version of the van Cittert-Zernike theorem. More specifically, we
demonstrate that it is possible to exploit scattering and interference effects
in a propagating multiphoton system to control its quantum properties of
coherence. Furthermore, we show that the implementation of conditional
measurements enables the preparation of multiphoton systems with attenuated
quantum statistics below the shot-noise limit. We believe that the multiphoton
quantum van Cittert-Zernike theorem will have important implications for
describing the evolution of the properties of quantum coherence of many-body
bosonic systems.
