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 1):
A quantum computation device, comprising:\n a plurality of photon generators, each photon generator further comprising:\n a ring resonator disposed in a chip; \n a first optical channel disposed in said chip, said first optical channel having a first input and a first output, said first input and said first output being in common with each other and with said input to said chip;\n said first optical channel being tangential to said ring resonator at a first point and a second point; and \n \n a second optical channel disposed in said chip, said second optical channel having a second input and a second output;\n said second optical channel being tangential to said ring resonator at a third point and a fourth point; \n \n a first plurality of optical couplers, each optical coupler corresponding to one of said plurality of photon generators in a one-to-one fashion for coupling said second input and said second output of said photon generator so as to produce entangled photon states; a reconfigurable optical switch network for matrixing connections between outputs of said first plurality of optical couplers and inputs of a second plurality of optical couplers; a second plurality of optical couplers, each corresponding to and each being reconfigurably connected via said reconfigurable optical switch network to any one of said first plurality of optical couplers; a third plurality of optical couplers, each connected to each of a corresponding second plurality of optical couplers so as to further entangle said photon states; phase shifting elements\n between each of said plurality of photon generators and each of said corresponding first plurality of optical couplers; and \n between each of said second plurality of optical couplers and each of said corresponding third plurality of optical couplers so as to compensate for optical length and timing differences; and \n a plurality of photodetectors for indicating said entangled photon states output from said third plurality of optical couplers so as to facilitate computations therefrom.
