Quantum repeaters and memories are needed to overcome efficiently the losses of long-distance quantum networks [1]. A promising system to host a quantum memory is atomic vapours, which can be enhanced with guiding photonic structures [2].
We will present a simulation program and experimental measurements for enhanced light matter interaction in hollow-core light-cages (LC) inside a warm cesium vapor cell. The program calculates the absorption spectra of alkali vapors under Electromagnetically Induced Transparency (EIT). Propagation of light pulses through the bare atomic vapor and the LC are simulated, where a linear loss model is assumed. This use of the LC would lead towards controllable time delay of photons in an easy to use and easy to implement device and eventually a reliable platform for a quantum memory for single photons using the EIT-storage scheme [3].
