Nonlinear-linear duality for multipath quantum interference
Yi Zheng, Jin-Shi Xu, Chuan-Feng Li +1
In quantum optics, the postselection amplitude of a nondegenerate parametric down-conversion (PDC) process is linked to a beamsplitter (BS) via partial time reversal, up to a norma…
Position-correlated biphoton wavefront sensing for quantum adaptive imaging
Yi Zheng, Zhao-Di Liu, Jian-Shun Tang +3
Quantum imaging with spatially entangled photons offers advantages such as enhanced spatial resolution, robustness against noise, and counter-intuitive phenomena, while a biphoton…
Theory of the monochromatic advanced-wave picture and applications in biphoton optics
Yi Zheng, Jin-Shi Xu, Chuan-Feng Li +1
Klyshko's advanced-wave picture (AWP) is mainly interpreted by replacing the nonlinear crystal producing biphotons via spontaneous parametric down-conversion (SPDC) by a mirror in…
Characterizing Biphoton Spatial Wave Function Dynamics with Quantum Wavefront Sensing
Yi Zheng, Zhao-Di Liu, Rui-Heng Miao +6
With an extremely high dimensionality, the spatial degree of freedom of entangled photons is a key tool for quantum foundation and applied quantum techniques. To fully utilize the…
