Abstract

Linear optics quantum computation (LOQC) eliminates the need for a strongly nonlinear photon-photon interaction to create entangling gate operation, instead replacing it with the fundamental nonlinearity of quantum measurement. The LOQC gates rely on nondeterministic performance conditioned on detection or nondetection of events in ancillary modes, and are normally characterized in the multiple photon basis in which they are designed to operate. By assuming that the underlying physical structure of an LOQC gate is linear, and therefore describable entirely by it's action on single-photon input states, it is possible to exponentially reduce the number of parameters necessary to characterize that gate.
