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 keep atoms/molecules 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 matastable energy levels.

摘要： A photonic interconnect system (300) 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 (600), modulators (660), and detectors (650) for the photonic interconnect system can be efficiently fabricated at defects in a photonic bandgap crystal.

摘要： Photon resolving detectors with near unit detection efficiency distinguish between a target state including n phontons and a target state including n+1 photons by measuring a change such as a phase shift or attenuation that a probe photon state receives in a quantrum gate. The detection does not destroy the phonons from the target state, so that photons can be used after detection. A system using a non-destructive detector in conjunction with one or more signgle photon storage system can store a determined number of photons and release one or more stored phontons when required to produce a photon state including a determined number of photons.

摘要： A device capable of efficiently detecting a single-photon signal includes a matter system (112), sources (114 and 610) of a first beam and a second beam, and a measurement (420) system. The matter system (112) has a first energy level and a second energy level such that a signal photon couples to a transition between the first energy level and the second energy level. The first beam contains photons that couple to a transition between the second energy level and a third energy level of the matter system (112), and the second beam contains photons that couple to a transition between the third energy level and a fourth energy level of the matter system (112). The measurement system (420) measures a change in the first or second beam to detect the absence, the presence, or the number of the photons in the signal.

摘要： Nonlinear electromagnetic elements (210) can efficiently implement quantum information processing tasks such as controlled phase shifts, non-demolition state detection, quantum subspace projections, non-demolition Bell state analysis, heralded state preparation, quantum non-demolition encoding, and fundamental quantum gate operations. Direct use of electromsgnetic non-linearity can amplify small phase shifts and use feed forward systems (900) in a near deterministic manner with high operating efficiency. Measurements using homodyne detectors (530) can cause near deterministic projection of input states on a Hilbert subspace identified by the measurement results. Feed forward operation can then alter the projected state if desired to achieve a desired output with near 100% efficiency.

摘要： Various embodiments of the present invention are directed to methods and systems for circumventing, and altering transmission-channel users of, transmission-channel disruptions. In one embodiment of the present invention, a source (1602, 1702) encodes information in a first signal and transmits the first signal in a source channel (1610, 1712) to a multiplexer (1604, 1704). The multiplexer (1604, 1704) distributes the first signal over N transmission channels (1612, 1718). A demultiplexer (1606, 1806) combines the signals distributed over the N transmission channels (1612, 1718) into a second signal encoding of the information. The distribution system also includes a detector (1608,1730) that receives the second signal output from the demultiplexer (1606, 1706), and one or more detectors (1620, 1732) that receive one or more additional signals output from the demultiplexer (1606, 1706). The additional signals are produced by the demultiplexer (1606, 1706) when a disruption occurs in one or more of the transmission channels and are used to alert transmission-channel users of the disruption.
