Abstract:
Briefly stated, the invention provides an apparatus for quantum computing comprising optical integrated on-chip generation of photon pairs as building blocks to create entangled photon states which are detected as necessary for quantum information processing. The invention provided a frequency selective optical coupling device which controls the transmission of light by varying the relative dimensions of otherwise symmetrical linear optical waveguides tangential to an annular optical waveguide, thereby controlling the coupling of light between the linear optical waveguides and the annular optical waveguide. Dimensional change of the optical waveguides is achieved by a heated medium in proximity of the optical waveguides and under electronic control.

Claim (Index 13):
The quantum computation device of  claim 1 , wherein each of said plurality of photon generators comprises a ring resonator on a chip of nonlinear optical material; said ring resonator having two connections of an optical waveguide or channel on each side of said ring resonator such that each said side forms an asymmetric length Mach-Zehnder interferometer to filter pump light from signal/idler photons created in said nonlinear optical material ring resonator; inside said ring resonator pump photons are critically coupled into said resonator to facilitate maximum generation of said signal/idler photons in said nonlinear optical material ring resonator and which remain in a cavity inside said ring resonator; said signal/idler photons generated in said nonlinear optical material based ring resonator by the process of either spontaneous parametric downconversion and spontaneous four wave mixing are over coupled to said resonator cavity to allow for maximum brightness of generated signal/idler photons exiting said nonlinear optical material-based ring resonator while said pump photons remain in said ring resonator cavity.
