Query: Cavity enhanced storage - preparing for high efficiency quantum memories   Cavity assisted quantum memory storage has been proposed [PRA 82, 022310
(2010), PRA 82, 022311 (2010)] for creating efficient (close to unity) quantum
memories using weakly absorbing materials. Using this approach we
experimentally demonstrate a significant (about 20-fold) enhancement in quantum
memory efficiency compared to the no cavity case. A strong dispersion
originating from absorption engineering inside the cavity was observed, which
directly affect the cavity line-width. A more than 3 orders of magnitude
reduction of cavity mode spacing and cavity line-width from GHz to MHz was
observed. We are not aware of any previous observation of several orders of
magnitudes cavity mode spacing and cavity line-width reduction due to slow
light effects.
