Abstract: | I will describe two projects completed during my graduate career here at CQuIC, both of which are based on the interaction between a system and a traveling-wave quantum field. The first is a master equation approach for the reduced dynamics of an arbitrary system when the input field is prepared in a nonclassical state of definite photon number. To illustrate the somewhat complicated formalism, I will present some simple examples. The second is a three-dimensional light-matter interface for a spatially extended ensemble of alkali atoms probed by a paraxial quantum field in free space. We include both the collective coherent atom-light interaction and decoherence from local diffuse scattering. Using this model I will discuss spatial effects in quantum nondemolition spin squeezing for realistic experimental parameters. | |
