Narrowband biphoton generation near atomic resonance
Generating nonclassical light offers a benchmark tool for fundamental research and potential applications in quantum optics. Conventionally, it has become a standard technique to produce nonclassicalExpand
Temporal- and spectral-property measurements of narrowband photon pairs from warm double-Λ-type atomic ensemble.
TLDR
The temporal and spectral properties of narrowband photon pairs from a double-Λ-type atomic system of a warm 87Rb atomic ensemble and the spectral measurement of the photon pair is obtained by applying the stimulated emission method are investigated. Expand
Ultranarrow-bandwidth filter based on a thermal EIT medium
We present high-contrast electromagnetically-induced-transparency (EIT) spectra in a heated vapor cell of single isotope 87Rb atoms. The EIT spectrum has both high resonant transmission up to 67% andExpand
Bright narrowband biphoton generation from a hot rubidium atomic vapor cell
We demonstrate the generation of high-quality narrowband biphotons from a Doppler-broadened hot rubidium atomic vapor cell. Choosing a double-Λ atomic energy level scheme for optimizing bothExpand
Efficient generation of subnatural-linewidth biphotons by controlled quantum interference
Biphotons of narrow bandwidth and long temporal length play a crucial role in long-distance quantum communication (LDQC) and linear optical quantum computing (LOQC). However, generation of theseExpand
Narrow band source of transform-limited photon pairs via four-wave mixing in a cold atomic ensemble.
TLDR
Narrow band pairs of time-correlated photons from nondegenerate four-wave mixing in a laser-cooled atomic ensemble of ^{87}Rb using a cascade decay scheme are observed, indicating a transform-limited spectrum of the photon pairs. Expand
High nonclassical correlations of large-bandwidth photon pairs generated in warm atomic vapor
Generation of nonclassical light suitable for interaction with atoms corresponds to a crucial goal pursued across the broad quantum optics community. We present the generation of nonclassical photonExpand
Generation of correlated biphoton via four-wave mixing coexisting with multi-order fluorescence processes
TLDR
The biphoton temporal correlation is obtained from spontaneous parametric four-wave-mixing and fourth-order fluorescence processes, and may contribute potentially to the applications in dense coding quantum communication systems. Expand
Enhanced spectral profile in the study of Doppler-broadened Rydberg ensembles
TLDR
This work overcomes the obstacle of weak signal in the Rydberg-EIT spectrum caused by an apparent relaxation rate of the R Sydberg polariton and weak coupling transition strength, and provides the useful knowledge for the R Sydney EIT study. Expand
Subnatural-linewidth biphotons from a Doppler-broadened hot atomic vapour cell
TLDR
This work uses on-resonance spontaneous four-wave mixing in a hot paraffin-coated 87Rb vapour cell at 63 °C to produce biphotons with controllable bandwidth and coherence time, which may lead towards miniature narrowband biphoton sources. Expand
