Time-resolved correlation engineering in DLCZ Raman photon sources
Jiun-Shiuan Shiu, Chang-Wei Lin, Chi-Ming Yang +2
Memory-assisted quantum networks require photon sources with controllable temporal and correlation properties. The Duan-Lukin-Cirac-Zoller (DLCZ) protocol provides a platform based…
High-efficiency telecom conversion of heralded atomic biphoton wavepackets
Ling-Chun Chen, Chang-Wei Lin, Jiun-Shiuan Shiu +3
We demonstrate high-efficiency telecom frequency conversion of heralded atomic biphoton wavepackets using a diamond-type atomic ensemble. By placing a 2.5 MHz heralded-photon spect…
Microscopic Origin of Superradiant Biphoton Emission in Atomic Ensembles
Zi-Yu Liu, Jiun-Shiuan Shiu, Wei-Lin Chen +1
Superradiant biphoton emission from atomic ensembles provides a powerful route to generating highly correlated quantum light, yet its microscopic physical origin has remained incom…
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 angul…
High-efficiency telecom frequency conversion via a diamond-type atomic ensemble
Ling-Chun Chen, Meng-Yi Lin, Jiun-Shiuan Shiu +3
Efficient telecom frequency conversion (TFC) in atomic systems is crucial for integrating atom-based quantum nodes into low-loss fiber-optic quantum networks. Here, we demonstrate…
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-Î spontaneous four-wave mixing (SFWM) within a…
