We systematically studied the relation between the conditional auto-correlation function
(CACF) and cross-correlation function (CCF) of biphotons or pairs of single photons. 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 …

We report the generation of biphotons, with a temporal full width at the half maximum
(FWHM) of 13.4±0.3 µs and a spectral FWHM of 50±1 kHz, via the process of spontaneous …

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 …

We measure the joint temporal intensity of signal and idler photon pairs generated by
spontaneous four-wave mixing in a silicon nitride microresonator by time-resolved …

This review article focuses on biphoton sources based on the double‐Λ Λ spontaneous four‐
wave mixing (SFWM) process in laser‐cooled as well as room‐temperature or hot atomic …

The measurement of a quantum state wave function not only acts as a fundamental part in
quantum physics but also plays an important role in develo** practical quantum …

Utilizing the double-Λ spontaneous four-wave mixing (SFWM) process, the biphoton source
generates narrow-linewidth pairs of signal and probe photons. In a medium, the signal …

The large capacity and robustness of information encoding in the temporal mode of photons
is important in quantum information processing, in which characterizing temporal quantum …

We systematically studied the temporal profile of biphotons, pairs of time-correlated single
photons, generated from a hot atomic vapor via the spontaneous four-wave mixing process …
