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 4):
The quantum computation device of  claim 1 , wherein said photon generators each further comprise:\n a first filter having an output for selecting spectrally degenerate photons from said second input of said second optical channel; a second filter having an output for selecting spectrally degenerate photons from said second output of said second optical channel; a first predeterminable relative phase delay between said first optical channel and said second optical channel, so as to cause a variance in an amount of light traversing said first optical channel and said second optical channel as a function of the frequency of said light; a second predeterminable relative phase delay between said second input of said second optical channel and said second output of said second optical channel; at least one filter of a third filter group having an output in common with a first output of said plurality of outputs of said chip, where said at least one filter of said third filter group selects predetermined wavelengths of light from said phase delayed second input of said second optical channel; at least one filter of a fourth filter group each having an output in common with a second output of said plurality of outputs of said chip, where said at least one filter of said fourth filter group selects predetermined wavelengths of light from said phase delayed second output of said second optical channel; a third predeterminable relative phase delay between said first filter output and said second filter output; an optical coupling between said relative phase delayed first filter output and said relative phase delayed second filter output, said optical coupling having a first output and a second output; a third output of said plurality of outputs of said chip in common with said phase delayed second input of said second optical channel; a fourth output of said plurality of outputs of said chip in common with said phase delayed second output of said second optical channel; a fifth output of said plurality of outputs of said chip in common with said first output of said optical coupling; a sixth output of said plurality of outputs of said chip in common with said second output of said optical coupling; and an electronic control subsystem in operative communication with said chip for facilitating said predeterminable relative phase delays.
