Observation of Highly Correlated Ultrabright Biphotons Through Increased Atomic Ensemble Density in Spontaneous Four-Wave Mixing
Jiun-Shiuan Shiu, Zi-Yu Liu, Chin-Yao Cheng +7
The pairing ratio, a crucial metric assessing a biphoton source's ability to generate correlated photon pairs, remains underexplored despite theoretical predictions. This study pre…
Fisher information analysis on quantum-enhanced parameter estimation in electromagnetically-induced-transparency spectrum with single photons
Pin-Ju Tsai, Lun-Ping Yuan, Ying-Cheng Chen
Electromagnetically-induced-transparency (EIT) spectroscopy has been used as a sensitive sensor in quantum metrology applications. The sensitivity of a sensor strongly depends on t…
Temporally-ultralong biphotons with a linewidth of 50 kHz
Yu-Sheng Wang, Kai-Bo Li, Chao-Feng Chang +9
We report the generation of biphotons, with a temporal full width at the half maximum (FWHM) of 13.40.3 s and a spectral FWHM of 501 kHz, via the process of spontaneou…
Room-temperature biphoton source with a spectral brightness near the ultimate limit
Jia-Mou Chen, Chia-Yu Hsu, Wei-Kai Huang +7
The biphotons, generated from a hot atomic vapor via the process of spontaneous four-wave mixing (SFWM), have the following merits: stable and tunable frequencies as well as linewi…
Efficient frequency conversion based on resonant four-wave mixing
Chin-Yao Cheng, Zi-Yu Liu, Pi-Sheng Hu +8
Efficient frequency conversion of photons has important applications in optical quantum technology because the frequency range suitable for photon manipulation and communication us…
Generation of sub-MHz and spectrally-bright biphotons from hot atomic vapors with a phase mismatch-free scheme
Chia-Yu Hsu, Yu-Sheng Wang, Jia-Mou Chen +11
We utilized the all-copropagating scheme, which maintains the phase-match condition, in the spontaneous four-wave mixing (SFWM) process to generate biphotons from a hot atomic vapo…
