Multiple optical interactions for quantum gates

  • D. A. Antonosyan

We present results of quasi-phase matching (QPM) interactions in one-dimensional multilayered media consisting of layers with different χ(2) nonlinearities that interchanged by linear dispersive layers. We exploit the idea of manipulating overall group delay mismatches between the various fields in each layer by appropriate choosing of the dispersive parameters and consider both multiple optical QPM interactions and preparation of pure photon states in application to quantum gates.
