Adiabatic two-photon quantum gate operations using a long-range photonic bus

摘要: Adiabatic techniques have much potential to realize practical and robust optical waveguide devices. Traditionally, photonic elements are limited coupling schemes that rely on proximity nearest neighbour elements. We combine adiabatic passage with a continuum based long-range bus break free from such topological restraints thereby outline new approach quantum gate design. explicitly show designs for gates produce Hadamard, 50:50 1/3:2/3 beam splitter, non-deterministic controlled NOT planar thin, shallow ridge waveguides. Our calculations performed under conditions of one two-photon inputs.
