Quantum study of information delay in electromagetically induced transparency [PDF]

open access: yes, 2006
Using electromagnetically induced transparency (EIT), it is possible to delay and store light in atomic ensembles. Theoretical modelling and recent experiments have suggested that the EIT storage mechanism can be used as a memory for quantum information.
