- Abstract: The distributed quantum information processing and hybridization of quantum
platforms raises increasing demands on the quality of light-matter interaction
and realization of efficient quantum interfaces. This becomes particularly
challenging for needed states possessing fundamental quantum non-Gaussian (QNG)
aspects. They correspond to paramount resources in most potent applications of
quantum technologies. We demonstrate the generation of light with provably QNG
features from a tunable warm atomic ensemble in a single-mode regime. The light
is generated in a spontaneous four-wave mixing process in the presence of
decoherence effects caused by a large atomic thermal motion. Despite its high
sensitivity to any excess noise, a direct observability of heralded QNG light
could be achieved due to a combination of a fast resonant excitation, large
spectral bandwidth, and a low absorption loss of resonant photons guaranteed by
the source geometry.
