Quantum Phase Gate Operation Based on Nonlinear Optics: Full Quantum Analysis
C. Ottaviani, S. Rebic, D. Vitali +1
We present a full quantum treatment of a five-level atomic system coupled to two quantum and two classical light fields. The two quantum fields undergo a cross-phase modulation ind…

Coherently-assisted incoherent population transfer in a five-level system
S. Rebic, D. Vitali, C. Ottaviani +1
A novel effect of population transfer in a five-level system is analyzed. This population transfer effect is found to be a version of a Raman process, which is facilitated and assi…

A Proposal for an Optical Implementation of an Universal Quantum Phase Gate
S. Rebic, D. Vitali, C. Ottaviani +4
Large optical nonlinearities occurring in a coherently prepared atomic system are shown to produce phase shifts of order . Such an effect may be observed in ultracold rubidium a…
