TLDR
In this article, an optical memory is demonstrated in a kagome photonic crystal fiber whose 26-μm-diameter hollow core is loaded with cesium atoms, and Gigahertz-bandwidth light is stored using a far-detuned Raman interaction.Abstract:
An optical memory is demonstrated in a kagome photonic crystal fibre whose 26-μm-diameter hollow core is loaded with cesium atoms. Gigahertz-bandwidth light is stored using a far-detuned Raman interaction. It has a memory efficiency is 27 ± 1% and a signal-to-noise ratio of 2.6:1 — the highest at the single-photon level of any memory at room temperature.read more

Advances in quantum metrology
TL;DR: Quantum metrology is the use of quantum techniques such as entanglement to yield higher statistical precision than purely classical approaches as discussed by the authors, where the central limit theorem implies that the reduction is proportional to the square root of the number of repetitions.
