“…This shows the trade-off between the absorption of the signal itself and the re-absorption of the emitted echo. This is in good agreement with what have been observed experimentally in non-inverted mediums [20].…”

We present two quantum memory protocols for solids: A stopped light approach based on spectral hole burning and the storage in an atomic frequency comb. These procedures are well adapted to the rare-earth ion doped crystals. We carefully clarify the critical steps of both. On one side, we show that the slowing-down due to hole-burning is sufficient to produce a complete mapping of field into the atomic system. On the other side, we explain the storage and retrieval mechanism of the Atomic Frequency Comb protocol. This two important stages are implemented experimentally in Tm 3+ -doped yttrium-aluminum-garnet crystal.

“…This means that the excitation produced by the imperfect π pulse will no longer interact with the optical field (unless it is rephased by another strong pulse). The ability to prepare an ideal inverted medium for classical information processing has been investigated experimentally [30].…”

Nonclassical photon streams using rephased amplified spontaneous emission

We present a fully quantum mechanical treatment of optically rephased photon echoes. These echoes exhibit noise due to amplified spontaneous emission, however this noise can be seen as a consequence of the entanglement between the atoms and the output light. With a rephasing pulse one can get an "echo" of the amplified spontaneous emission, leading to light with nonclassical correlations at points separated in time, which is of interest in the context of building wide bandwith quantum repeaters. We also suggest a wideband version of DLCZ protocol based on the same ideas.

Photon-echo quantum memories in inhomogeneously broadened two-level atoms

et al. 2011

View full text Add to dashboard Cite

Here, we propose a solid-state quantum memory that does not require spectral holeburning, instead using strong rephasing pulses like traditional photon-echo techniques. The memory uses external broadening fields to reduce the optical depth and so switch off the collective atom-light interaction when desired. The proposed memory should allow operation with reasonable efficiency in a much broader range of material systems, for instance Er 3+ doped crystals which have a transition at 1.5 μm. We present analytic theory supported by numerical calculations and initial experiments.
