Abstract
A recently proposed, photon echo related approach to quantum state storage in atomic ensembles employs controlled reversible inhomogeneous broadening (CRIB). Beyond storage, a modified version of CRIB promises controlled quantum state manipulations. As the implementation of CRIB is currently still challenging, we investigate state transformation based on stimulated photon echoes. Specifically, we show how to translate an all optical, beamsplitter based setup into a photon echo based setup, and we simulate a photon echo based POVM (positive operator valued measure) measurement using Maxwell-Bloch equations.
