Engineering Spatial Entanglement of Photon Pairs Generated from Parametric Down-Conversion
So-Young Baek, Fumihiro Kaneda, Yasuyoshi Mitsumori, Keiichi Edamatsu · 2023
We present our recent progress on developing a parametric down-conversion source producing highly entangled photons in spatial mode toward quantum-enhanced spa-tial measurements. The degree of transverse spatial entanglement is engineered and characterized.
