Abstract: A quantum communications system includes a quantum key generation system having a photonic quantum bit generator, a dispersion compensating optical fiber link, and a photon detector unit and a communications network having a signal generator, a signal channel, and a signal receiver. The dispersion compensating optical fiber link extends between and optically couples the photonic quantum bit generator and the photon detector unit. Further, the dispersion compensating optical fiber link is structurally configured to induce dispersion at an absolute dispersion rate of about 9 ps/(nm)km or less and induce attenuation at an attenuation rate of about 0.18 dB/Km or less such that the quantum key bit information of a plurality of photons output by the one or more photonic quantum bit generators is receivable at the photon detector unit at a bit rate of at least about 10 Gbit/sec.

Abstract: A quantum communications system includes a quantum key generation system having a photonic quantum bit generator, a low loss dispersion limiting fiber having a length L, for example greater than 200 km, and a photon detector unit and a communications network having a signal generator, a signal channel, and a signal receiver. The low loss dispersion limiting fiber extends between and optically couples the photonic quantum bit generator and the photon detector unit. Further, the low loss dispersion limiting fiber is structurally configured to limit dispersion at an absolute dispersion rate of about 9 ps/(nm)km or less, and preferably 0.5 ps/(nm)km or less, and induce attenuation at an attenuation rate of about 0.175 dB/km or less such that the quantum key bit information of a plurality of photons output by the one or more photonic quantum bit generators is receivable at the photon detector unit at a bit rate of at least 10 Gbit/sec.

Abstract: A multicore optical fiber that includes a plurality of waveguiding cores disposed in a cladding. The plurality of waveguiding cores include one or more first waveguiding cores that have a first propagation constant and one or more second waveguiding cores that have a second propagation constant, where the first propagation constant differs from the second propagation constant. The one or more first waveguiding cores and the one or more second waveguiding cores are disposed in the cladding in a ring distribution and at least a portion of the ring distribution is arranged based on a quasi-periodic sequence having a plurality of sequence segments. Each sequence segment is determined based on a quasi-periodic function, has an order, and corresponds to an arrangement segment of a first waveguiding cores, a second waveguiding cores, or combinations thereof. The ring distribution includes at least one arrangement segment corresponding with a third-order sequence segment or higher of the quasi-periodic sequence.

Abstract: A multicore optical fiber that includes a plurality of waveguiding cores disposed in a cladding. The plurality of cores are situated adjacent to at least one other core with a core center to core center spacing being not larger than 10 times the radius of the average core, such that the greater than 10% of the light will couple from one core to the adjacent core over a propagating distance of 1 cm, along the fiber length so as to provide coupling between the adjacent cores and to enable quantum walk. The plurality waveguiding cores are disposed in the cladding in a ring distribution or at least a portion of the ring distribution.

Abstract: A quantum memory system includes a doped polycrystalline ceramic, a magnetic field generation unit, and one or more pump lasers. The doped polycrystalline ceramic is positioned within a magnetic field of the magnetic field generation unit when the magnetic field generation unit generates the magnetic field, the one or more pump lasers are optically coupled to the doped polycrystalline ceramic, and the doped polycrystalline ceramic is doped with a rare-earth element dopant that is uniformly distributed within a crystal lattice of the doped polycrystalline ceramic.

Abstract: Pressure-sensing touch systems and methods are disclosed for sensing the occurrence of a touch event based on pressure applied at a touch location. The touch system includes a light-source system and a detector system operably adjacent respective input and output edges of a waveguide. Pressure at a touch location on the waveguide gives rise to a touch event causes the waveguide to bend or flex. The waveguide bending causes a change in the optical paths of light traveling by FTIR, causing the light distribution in the output light to change. The changes are detected and are used to determine whether a touch event occurred, as well as the time-evolution of the touch event. The changes in the output light can include polarization changes caused by birefringence induced in the waveguide by the applied pressure applied. Various detector configurations are disclosed for sensing the location and pressure of a touch event.

Abstract: A method of communicating information includes generating a photon pulse using an entangled photon generator. The photon pulse includes a photon pulse state and is temporally positioned within a photon pulse time slot. When the photon pulse is in a populated photon pulse state, it includes first and second entangled photons and the entangled photon generator outputs the first entangled photon into a first photon pathway optically coupled to an output end photon detector unit, and the second entangled photon into a second photon pathway, optically coupled to a receiving end photon detector unit. The method also includes determining the photon pulse state of the photon pulse using the output end photon detector unit, which outputs a signal regarding the photon pulse state of the photon pulse into a signal pathway to provide the receiving end photon detector unit with information regarding the photon pulse state of the photon pulse.

Abstract: A material system for a surface display unit that includes a first side (i.e., a proximal side) that faces a viewer of the surface display unit and a second side (i.e., a distal side) facing away from the viewer. The material system provides at least three appearance states, including a generally opaque first appearance state when the surface display unit is “off” (i.e., not used to display images), a second appearance state in which the material system is illuminated from the first (i.e., proximal) side to display a first image (e.g., information and/or decoration) that is perceptible to the viewer, and a third appearance state in which the material system is illuminated from the second (i.e., distal) side to display a second image (e.g., information and/or decoration) that is perceptible to the viewer. Surface display units, systems, and methods comprising the material system are also disclosed.
