Manipulation and storage of optical field and atomic ensemble quantum states
arXiv:quant-ph/0407238
Abstract
We study how to efficiently manipulate and store quantum information between optical fields and atomic ensembles. We show how various non-dissipative transfer schemes can be used to transfer and store quantum states such as squeezed vacuum states or entangled states into the long-lived ground state spins of atomic ensembles.
