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…

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…

Low-Loss High-Fidelity Frequency-Mode Hadamard Gates Based on Electromagnetically Induced Transparency
Kao-Fang Chang, Ta-Pang Wang, Chun-Yi Chen +5
A frequency beam splitter (FBS) with the split ratio of 0.5 or 1 can be used as the frequency-mode Hadamard gate (FHG) for frequency-encoded photonic qubits or as the quantum frequ…
