    Abstract: A method of aligning first and second mating surfaces includes: generating a random or pseudo-random function; convolving the random or pseudo-random function with a spread function to produce a correlated function; forming a pattern of bi-polar material on the first mating surface based on a quantization of the correlated function; and forming a complementary pattern of the bi-polar material on the second mating surface. The complementary patterns exert a force on each other toward a desired alignment of the first and second mating surfaces. A system includes a first member having a first correlated pattern of material disposed on a first mating surface; and a second member having a second correlated pattern of material disposed on a second mating surface, wherein the second correlated pattern is complementary to the first correlated pattern.

  • Patent number: 7560726
    Abstract: Quantum information processing structures and methods use photons and four-level matter systems in electromagnetically induced transparency (EIT) arrangements for one and two-qubit quantum gates, two-photon phase shifters, and Bell state measurement devices. For efficient coupling of the matter systems to the photons while decoupling the matter systems from the phonon bath, molecular cages or molecular tethers maintain the atoms within the electromagnetic field of the photon, e.g., in the evanescent field surrounding the core of an optical fiber carrying the photons. To reduce decoherence caused by spontaneous emissions, the matter systems can be embedded in photonic bandgap crystals or the matter systems can be selected to include metastable energy levels.

  • Patent number: 7546004
    Abstract: A photonic interconnect system avoids high capacitance electric interconnects by using optical signals to communicate data between devices. The system can provide massively parallel information output by mapping logical addresses to frequency bands, so that modulation of a selected frequency band can encode information for a specific location corresponding to the logical address. Wavelength-specific directional couplers, modulators, and detectors for the photonic interconnect system can be efficiently fabricated at defects in a photonic bandgap crystal. The interconnect system can be used for both classical and quantum information processing.
