| dc.description.abstract | This thesis presents a method for generating nonlinear phase shifts on superpositions of photon number states. Light is stored in a Bose-Einstein condensate (BEC) via electromagnetically induced transparency (EIT) memory techniques. Atomic collisions are exploited to generate a nonlinear phase shift of the stored state. The stored light is then revived with the nonlinear phase shift imprinted upon it. We show that this method can be used to develop a nonlinear-sign gate in the regime where the Thomas-Fermi and mean-field approximations are valid. We test these approximations using realistic parameters to find that these approximations pass the standard tests for validity in a single-component condensate. However, for the two-component condensates considered here, we find that these conditions are not sufficiently strict. Therefore, we find a stronger set of conditions and show for the same set of parameters that the approximations are invalid. | en_US |
