Adiabatic Splitting, Transport, and Self-Trapping of a Bose-Einstein Condensate in a Double-Well Potential
C. Ottaviani, V. Ahufinger, R. Corbalán +1
We show that the adiabatic dynamics of a Bose-Einstein condensate (BEC) in a double well potential can be described in terms of a dark variable resulting from the combination of th…
Assessment of a quantum phase gate operation based on nonlinear optics
S. Rebic, C. Ottaviani, G. Di Giuseppe +2
We analyze in detail the proposal for a two-qubit gate for travelling single-photon qubits recently presented by C. Ottaviani \emph{et al}. [Phys. Rev. A \textbf{73}, 010301(R) (20…
Cross phase modulation in a five--level atomic medium: Semiclassical theory
Carlo Ottaviani, Stojan Rebic, David Vitali +1
The interaction of a five-level atomic system involving electromagnetically induced transparency with four light fields is investigated. Two different light-atom configurations are…
Polarization phase gate with a tripod atomic system
S. Rebic, D. Vitali, C. Ottaviani +4
We analyze the nonlinear optical response of a four-level atomic system driven into a tripod configuration. The large cross-Kerr nonlinearities that occurr in such a system are sho…
