Learning high-dimensional quantum entanglement through physics-guided neural networks

Yang Xu, Hao Zhang, Wenwen Zhang +4

High-gain spontaneous parametric down-conversion (SPDC) produces bright squeezed vacuum with rich high-dimensional entanglement, but its output is inherently multimodal and non-per…

Self-focusing of high-intensity beams with grid structures

Jiaqi Wang, Yang Xu, Saumya Choudhary +2

Laser beams with high optical power propagating in a Kerr medium can undergo self-focusing when their power exceeds a critical power determined by the optical properties of the med…

Optimal propagation distance for maximal biphoton entanglement through the weakly turbulent atmosphere

Luchang Niu, Saleem Iqbal, Yang Xu +1

Understanding the influence of atmospheric turbulence on the propagation of entangled biphoton states is essential for free-space quantum communication protocols. Using the extende…

Hybrid Deep Reconstruction for Vignetting-Free Upconversion Imaging through Scattering in ENZ Materials

Hao Zhang, Yang Xu, Wenwen Zhang +10

Optical imaging through turbid or heterogeneous environments (collectively referred to as complex media) is fundamentally challenged by scattering, which scrambles structured spati…

High-fidelity spatial information transfer through dynamic scattering media by an epsilon-near-zero time-gate

Yang Xu, Saumya Choudhary, Long D. Nguyen +7

Transparent conducting oxides (TCO) such as indium-tin-oxide (ITO) exhibit strong optical nonlinearity in the frequency range where their permittivities are near zero. We leverage…
