Efficiencies for the single mode operation of a quantum optical
nonlinear shift gate
Kunihiro Kojima, Holger F. Hofmann, Shigeki Takeuchi, Keiji Sasaki
abstract: We investigate the single mode operation of a quantum optical nonlinear \pi
phase shift gate implemented by a single two-level atom in one-dimensional free
space. Since the single mode property of the input photons at the atom is not
preserved in the interaction at the atom, we analyze the effeciency of single
mode operation that can still be achieved. We show how the input pulse shape
can be optimized to obtain high efficiencies for the nonlinear single mode
operation. With this analysis, we obtain an optimal single mode transmittance
per photon of 78% for the successful nonliner \pi phase shift operation.
