Polarization Entanglement in Atomic Biphotons via OAM-to-Spin Mapping
Chang-Wei Lin, Yi-Ting Ma, Jiun-Shiuan Shiu +1
We demonstrate polarization-entangled biphotons in a cold-atom double- system, overcoming atomic selection rules that suppress polarization correlations and favor orbital angula…

Asymmetric Biphoton Generation under Ground-State Decoherence and Phase Mismatch in a Cold Atomic Ensemble
Jiun-Shiuan Shiu, Chang-Wei Lin, Yong-Fan Chen
We present an experimental investigation of how ground-state decoherence and phase mismatch influence biphoton generation in double-Λ spontaneous four-wave mixing (SFWM) within a c…
