1. A method for state transfer in photonic quantum information processing, comprising:
obtaining an optical beam;
optically coupling a first waveguide to a second waveguide, the first and second waveguide having different geometries respectively;
providing the beam to said optically coupled waveguides to detune the beam, said detuning being a function of said respectively different geometries, said detuned coupling thereby providing population transfer between said first and second waveguides that preserves quantum states; and
using composite segments to provide quantum gates.
