Inverse Design of Quantum Holograms in Three-Dimensional Nonlinear Photonic Crystals

This work addresses the challenge of precise quantum correlation generation in photonics, which is incremental as it builds on existing design methods with a differentiable approach.

The authors tackled the problem of designing 3D nonlinear photonic crystals and pump beams to generate specific quantum correlations in structured photon-pairs, achieving this through a fully differentiable model that enables accurate and efficient learning and discovery of novel designs.
