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…

Polarization qubit phase gate in driven atomic media
Carlo Ottaviani, David Vitali, Maurizio Artoni +2
We present here an all--optical scheme for the experimental realization of a quantum phase gate. It is based on the polarization degree of freedom of two travelling single photon w…
