Maps of Broadband Quantum Memory Based on an Atomic Frequency Comb

Resumo

The influence of the parameters of an inhomogeneously broadened optical transition in the shape of an atomic frequency comb on dispersion effects in the quantum-memory protocol implemented in such an atomic system is investigated. The results allowed maps to be constructed of dispersion and quantum efficiency for implementation of the studied protocol in rare-earth-doped crystals that are promising for creation of a quantum repeater.
