Physical Review Applied, 2024•APSAccurately controlling the quantum coherence of photons is pivotal for their applications in
quantum sensing and quantum imaging. Here, we propose the utilization of quantum
entanglement and local phase manipulation techniques to control the higher-order quantum
coherence of photons. By engineering the spatially varying phases in the transverse plane,
we can precisely manipulate the spatial structure of the second-order coherence function of
entangled photon pairs without changing the photon intensity distribution of each photon …

Accurately controlling the quantum coherence of photons is pivotal for their applications in quantum sensing and quantum imaging. Here, we propose the utilization of quantum entanglement and local phase manipulation techniques to control the higher-order quantum coherence of photons. By engineering the spatially varying phases in the transverse plane, we can precisely manipulate the spatial structure of the second-order coherence function of entangled photon pairs without changing the photon intensity distribution of each photon. Our approach can readily be extended to higher-order quantum coherence control. These results could potentially stimulate experimental research and applications of optical quantum coherence.
