    摘要: 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.

    摘要: Embodiments of the present invention include dense, but accessible and well-interconnected component arrangements within multi-component systems, such as high-end multi-processor computer systems, and methods for constructing such arrangements. In a described embodiment, integrated-circuit-containing processing components, referred to as a “flat components,” are arranged into local blocks of intercommunicating flat components. The local flat-component blocks are arranged into interconnected, primitive multi-local-block repeating units, and the primitive local-block repeating units are layered together in a three-dimensional, regularly repeating structure that can be assembled to approximately fill any specified three-dimensional volume. The arrangement provides for relatively short, direct pathways from the surface of the specified volume to any particular local block and flat component within the three-dimensional arrangement.

    摘要: A sensor includes traps that are adjacent to a waveguide and capable of holding a contaminant for an interaction with an evanescent field surrounding the waveguide. When held in a trap, a particle of the contaminant, which may be an atom, a molecule, a virus, or a microbe, scatters light from the waveguide, and the scattered light can be measured to detect the presence or concentration of the contaminant. Holding of the particles permits sensing of the contaminant in a gas where movement of the particles might otherwise be too fast to permit measurement of the interaction with the evanescent field. The waveguide, a lighting system for the waveguide, a photosensor, and a communications interface can all be fabricated on a semiconductor die to permit fabrication of an autonomous nanosensor capable of suspension in the air or a gas being sensed.
