Apparatus and methods for performing quantum computations are disclosed. Such apparatus and methods may include identifying a first quantum state of a lattice having a system of quasi-particles disposed thereon, moving the quasi-particles within the lattice according to at least one predefined rule, identifying a second quantum state of the lattice after the quasi-particles have been moved, and determining a computational result based on the second quantum state of the lattice. Various platforms can be used to physically implement such a quantum computer. Platforms include an optical lattice, a Josephson junction array, a quantum dot, and a crystal structure. Each platform comprises an appropriate array of associated sites that can be used to approximate a desired Kagome geometry. A charge controller is desirably electrically coupled to the platform so that the array may be manipulated as desired. A computing device may be coupled to the charge controller and / or the platform to provide instructions and support, record measurements, and make calculations, for example.

Various embodiments improve accuracy by increasing the number of atoms engaged in a clock transitions in an optical lattice clock. An exemplary optical lattice clock an embodiment comprises an optical waveguide, an optical path, a laser light source, and a laser cooler. The optical path has a hollow pathway that extends from a first end to a second end while being surrounded with a tubular wall, which is used as a waveguide path. The optical path passes between mirrors and through the pathway. The laser light source supplies to the optical path a pair of lattice lasers (L1 and L2) propagating in opposite directions with each other. The laser cooler supplies cooled atoms that have two levels of electronic states associated with a clock transition to the vicinity of the first end of the optical waveguide.

A multi-section filter is provided for use in processing optical signals and other signals that can be readily projected from one filter section to another. Filters of the invention can be configured in numerous forms, including IIR and FIR filters and both linear and 2D active optical lattice filters. Filter sections are coupled together by means of four direction couplers and surface grating couplers, and may be implemented as GSE photonic integrated circuit devices.

The invention provides a method and a system for improving display effect of optical lattice images. Images consist of light spot arrays are reduced optically by a first optical element so as to generate a first optical image on a first imaging part with scattering effect, and until the space between light spots in the first optical image is less than or equal to the size of the light spot in an optical image, gaps do not exist between the light spots in the first optical image; and the first optical image is amplified optically by using a second optical element to form a second optical imageof a light spot image on a second imaging part. By adopting the technique of the invention, the images after optical processing of the lattice images do not have lattice gaps when presented to people, thus, a smooth image feeling is provided to a viewer, the aim of improving the image display effect is achieved and further the image quality is improved. Simultaneously, the technique of the invention can also be used for designing new projection devices and illuminating systems.
