Fundamental limit on the heralded single photons' spectral brightness
Tse-Yu Lin, Wei-Kai Huang, Pei-Yu Tu +2
Heralded single photons (HSPs) are the versatile flying qubits in quantum communication and networks due to their ability to remove the randomness of arrival time and enhance the t…
Temporally-long C-band heralded single photons generated from hot atoms
Pei-Yu Tu, Chia-Yu Hsu, Wei-Kai Huang +3
C-band photons are recognized for having the lowest loss coefficient in optical fibers, making them highly favorable for optical fiber-based communication. In this study, we system…
Protecting Heralded Single Photons Generated from Double- Biphoton Sources with Doppler-Broadened Atomic Media
Wei-Kai Huang, Tse-Yu Lin, Pei-Yu Tu +2
Biphoton sources that use room-temperature or hot atoms are valuable for real-world applications in long-distance quantum communication and photonic quantum computation. The herald…
Observation of Subnatural-Linewidth Biphotons In a Two-Level Atomic Ensemble
Jyun-Kai Lin, Tzu-Hsiang Chien, Chin-Te Wu +4
Biphotons and single photons with narrow bandwidths and long coherence times are essential to the realization of long-distance quantum communication (LDQC) and linear optical quant…
