1. A quantum optical switch, comprising:
a linear waveguide;
a nonlinear waveguide evanescently coupled to the linear waveguide; and
an optical pump field coupled to the nonlinear waveguide,
wherein the nonlinear waveguide is quasi-phase matched to support quantum frequency transduction of signal photons by the optical pump field to enable switching.
