Electromagnetically-induced transparency assists the Raman gradient echo memory at moderate detuning, dependent on gradient order

Optical quantum memories are essential for quantum communications and photonic quantum technologies.Ensemble optical memories based on 3-level interactions are a popular basis for Doors implementing these memories.All such memories, however, suffer from loss due to scattering.In off-resonant 3-level interactions, such as the Raman gradient echo mem
