A method for designing artificial impedance surfaces is disclosed. The method involves matching impedance component values required for a given far-field radiation pattern (determined, for example, by holographic means) with measured or simulated impedance component values for the units of a lattice of conductive structures used to create an artificial impedance surface, where the units of the lattice have varied geometry. For example, a unit could be a square conductive structure with a slice (removed or missing material) through it. The measured or simulated impedance components are determined by measuring wavevector values for test surfaces in three or more directions over any number of test surfaces, where each unit of a given test surface has the same geometric shape and proportions as all of the other units of that test surface, but each test surface has some form of variation in the unit geometry from the other test surfaces. These test measurements create a table of geometry vs. impedance components that are used to design the artificial impedance structure. Since polarization can be controlled, the structure can be an artificial impedance surface characterized by a tensor impedance having complex components.

Described is a scalable quantum computer that includes at least two classical to quantum interface devices, with each being connected to a distinct quantum processing unit (QPU). An Einstein-Podolsky-Rosen pair generator (EPRPG) is included for generating an entangled Einstein-Podolsky-Rosen pair that is sent to the QPUs. Each QPU is quantumly connected with the EPRPG and is configured to receive a mobile qubit from the EPRPG and perform a sequence of operations such that the mobile qubit interacts with a source qubit when a teleportation algorithm is initiated, leaving a second mobile qubit in the original quantum state of the source qubit.

An artificial impedance structure and a method for manufacturing same. The structure contains a dielectric layer having generally opposed first and second surfaces, a conductive layer disposed on the first surface, and a plurality of conductive structures disposed on the second surface to provide a preselected impedance profile along the second surface.

A method for guiding waves over objects, a method for improving a performance of an antenna, and a method for improving a performance of a radar are disclosed. The methods disclosed teach how an impedance structure can be used to guide waves over objects.
