Entangled and disentangled evolution for a single atom in a driven cavity | | J. Gea-Banacloche

24 Sep 2004 | | Subject: | quant-ph | | Abstract: | For an atom in an externally driven cavity, we show that special initial states lead to near-disentangled atom-field evolution, and superpositions of these can lead to near maximally-entangled states. Somewhat counterintutively, we find that (moderate) spontaneous emission in this system actually leads to a transient increase in entanglement beyond the steady-state value. We also show that a particular field correlation function could be used, in an experimental setting, to track the time evolution of this entanglement. | | Source: | arXiv, quant-ph/0409164 | | Services: | Forum | Review | PDF | Favorites | |
