Superluminal propagation via coherent manipulation of the Raman gain process
(Physical Review A, 2004-08-12)
We present a method of manipulating the Raman process by using a coherent control field which leads to splitting of the Raman gain peak into a doublet and anomalous dispersion in the region between the gain peaks. We show ...
Implementing Deutsch-Jozsa algorithm using light shifts and atomic ensembles
(Physical Review A, 2005-01-27)
We present an optical scheme to implement the Deutsch-Jozsa algorithm using ac Stark shifts. The scheme uses an atomic ensemble consisting of four-level atoms interacting dispersively with a field. This leads to a Hamiltonian ...
