Measurement-induced Nonlinearity in Linear Optics
arXiv:quant-ph/0305082 · doi:10.1103/PhysRevA.68.032310
Abstract
We investigate the generation of nonlinear operators with single photon sources, linear optical elements and appropriate measurements of auxiliary modes. We provide a framework for the construction of useful single-mode and two-mode quantum gates necessary for all-optical quantum information processing. We focus our attention generally on using minimal physical resources while providing a transparent and algorithmic way of constructing these operators.
