We observe narrow band pairs of time-correlated photons of wavelengths 776 and 795 nm
from nondegenerate four-wave mixing in a laser-cooled atomic ensemble of Rb 87 using a …

Entangled photon pairs, termed as biphotons, have been the benchmark tool for
experimental quantum optics. The quantum-network protocols based on photon–atom …

The ideal single-photon source displaying high brightness and purity, emission on-demand,
mature integration, practical communication wavelength (ie, in the telecom range), and …

The distribution of high-fidelity high-rate entanglement over telecommunication infrastructure
is one of the main paths toward large-scale quantum networks, enabling applications such …

Nonlinear optics has been a very dynamic field of research with spectacular phenomena
discovered mainly after the invention of lasers. The combination of high intensity fields with …

CMOS-compatible photonic chips are highly desirable for real-world quantum optics devices
due to their scalability, robustness, and integration with electronics. Despite impressive …

We experimentally generate a non-classical correlated two-color photon pair at 780 and
1529.4 nm in a ladder-type configuration using a hot^ 85Rb atomic vapor with the …

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 …

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 …
