  • Patent number: 9728835
    Abstract: A switching device includes a first electrode at least partially disposed within a sealed chamber. The sealed chamber encloses a plasma phase change material. The switching device includes a second electrode at least partially disposed within the sealed chamber. The second electrode is physically separated from the first electrode. When subjected to a signal that satisfies a threshold, the plasma phase change material forms a plasma within the sealed chamber. The first electrode is electrically coupled to the second electrode via the plasma when the plasma is formed. The first electrode is electrically isolated from the second electrode when the plasma is not formed. The switching device includes a first connector electrically coupled to the first electrode and a second connector electrically coupled to the second electrode. The first connector, the second connector, or both, are configured to receive the signal.

  • Patent number: 9692523
    Abstract: Methods of digital communication utilizing entangled qubits are disclosed. The communication methods exploit selective entanglement swapping to transfer an entangled state between a sending device and a receiving device. Each device includes pairs of qubits that are independently entangled with pairs of qubits in the other device. By selectively entangling the qubits within a pair in the sending device, the qubits of the corresponding pair in the receiving device also are selectively entangled. When the qubits are entangled, they are projected onto a particular entangled state type. Though no information may be transferred through selective entanglement of one qubit pair, the disclosed methods determine whether a set of pairs of qubits are entangled by determining whether the distribution of pairs is a correlated or uncorrelated distribution (a probabilistic approach) and transform the distribution type to a classical bit of data to transfer classical bits in a qubit-efficient approach.

  • Patent number: 9350461
    Abstract: Systems and methods for digital communication utilizing entangled qubits are disclosed. The disclosed systems and methods exploit selective entanglement swapping to transfer an entangled state between sites. Each site includes pairs of qubits that are independently entangled with pairs of qubits at the other site. By selectively entangling the qubits within a pair at one site, the qubits of the corresponding pair at the other site also are selectively entangled. When the qubits are entangled, they are projected onto a particular entangled state type. Though no information may be transferred through selective entanglement of one qubit pair, systems and methods of the present disclosure determine whether a set of pairs of qubits are entangled by determining whether the distribution of pairs is a correlated or uncorrelated distribution (a probabilistic approach) and transform the distribution type to a classical bit of data.

  • Patent number: 9134422
    Abstract: An ultraviolet laser generates a coherent beam, which is downconverted to produce pairs of frequency-entangled photons. For each entangled pair, a first photon is sent along a first path and a second photon is sent along a second path. A first detector detects those photons sent along the first path, and a second detector detects those photons sent along the second path. The detection is performed in a single photon regime. Coincidence counting is performed on outputs of the detectors, including comparing leading edges on outputs of the first and second detectors within a time window.

  • Patent number: 8493277
    Abstract: A leaky cavity resonator that includes a waveguide, the waveguide being filled with a dielectric material, and at least two complementary split ring resonators (CSRRs), the CSRRs residing inside the waveguide parallel to each other placed symmetrically both radially and in height, a leaky resonant cavity being formed between the at least two CSRRs and a wall of the waveguide. A frequency band of the leaky cavity resonator is adjustable by varying a distance w between at least one outside perimeter of at least one CSRR and an interior wall of the waveguide. A frequency band of the leaky cavity resonator is also adjustable by varying a size of the leaky resonant cavity. The at least two CSRRs each have at least one stub connecting to a wall of the waveguide. A frequency band of the leaky cavity resonator is also adjustable by varying a size of the stubs.

  • Patent number: 8269978
    Abstract: An object that might be at least partially obscured is imaged. Frequency-entangled photons are generated. The frequency-entangled photons include photons having first and second frequencies. Those photons having the first frequency can pass through the obscuration and illuminate the object. Photons scattered by the object and those photons having the second frequency are used to form an image by considering coincidences in time of arrival.

  • Patent number: 8240609
    Abstract: A metamaterial has a magnetic permeability response at frequencies sufficient to generate a repulsive force between a fluid and a surface to which the metamaterial may be applied. The metamaterial may be nanofabricated such that an absolute value of the magnetic permeability of the metamaterial is substantially greater than an absolute value of an electric permittivity of the metamaterial. The metamaterial may generate a repulsive force between the surface and the fluid moving relative to the surface and thereby reduce viscous drag of the fluid on the surface. A method of reducing the viscous drag of the fluid moving past the surface includes producing relative motion between the surface and the fluid and generating the repulsive force between the surface and the fluid.

  • Patent number: 8130171
    Abstract: A method and apparatus for a negative index metamaterial lens. The method is used for creating a negative index metamaterial lens for use with a phased array antenna. A design is created for the negative index materials lens that is capable of bending a beam generated by the phased array antenna to around 90 degrees from a vertical orientation to form an initial design. The initial design is modified to include discrete components to form a discrete design. Materials are selected for the discrete components. Negative index metamaterial unit cells are designed for the discrete components to form designed negative index metamaterial unit cells. The designed negative index metamaterial unit cells are fabricated to form fabricated designed negative index metamaterial unit cells. The negative index metamaterial lens is formed from the designed negative index metamaterial unit cells.

  • Patent number: 7928892
    Abstract: A system or method of creating a map of voids in the ground based on a scattered electromagnetic signal includes traversing a receiver/probe in a near field above a target area; generating a signal from a signal transmitter, the signal having a predetermined wavelength ?; receiving a scattered signal with the receiver/probe, the scattered signal including indications of subsurface variations via reflection of the generated signal; and detecting evanescent components of the scattered signal to provide a predetermined resolution. The method includes the use of an electrically small antenna for resolution of subwavelength features.
