Real-Space Analysis of Two-Photon Polarization States in Type-II SPDC for High-Purity Polarization Entanglement
Koji Taninaka, Takashi Kakue, Ken Morita
Spontaneous parametric down-conversion (SPDC) is one of the most widely used sources of polarization-entangled photon pairs, and understanding the generated biphoton state is essen…

Geometric Hybrid Poincaré Sphere with Variable Poles
Chihiro Tago, Takashi Kakue, Ken Morita
We propose a geometric hybrid Poincaré sphere (GHPS) as a unified geometrical framework for describing structured photon states with independently controllable spin angular momentu…
