摘要： There is described an adiabatic edge coupler comprising two coupled waveguides. A first waveguide extends from a tip width to a terminal width. A second waveguide comprises a first tapered portion that extends from a tip width to an intermediate width, and a second tapered portion that extends from the intermediate width to a terminal width. Upon receipt of an input optical signal, a coupled mode is formed between the two coupled waveguides. Over the first tapered portion, the coupled mode is adiabatically transformed onto the first waveguide. The coupled mode then decouples from the second waveguide over the second tapered portion. The adiabatic transformer enables low loss, small footprint, and fabrication-tolerant in-chip propagation of the coupled mode with relatively simplified fabrication processes and small critical dimensions.

摘要： A means of enabling an imaging lens system that overcomes some of the costs and disadvantages of the prior art is disclosed. A lens system in accordance with the present invention reduces or eliminates one or more aberrations of an optical input by separating image collection functionality from image processing functionality. As a result, each function can be performed without compromising the other function. An embodiment of the present invention comprises a collection optic that provides a first optical field, based on light from a scene, to a processing optic that comprises a plurality of lenslets. The processing optic tiles the first optical field into a plurality of second optical fields. Each lenslet receives a different one of the plurality of second optical fields, reduces at least one localized aberration in its received second optical field, and provides the corrected optical field to a different one of plurality of photodetectors whose collective output is used to form a spatially correlated sub-image of that corrected optical field. The sub-images are readily combined into a spatially correlated image of the scene.

摘要： The disclosure provides a scalable fault-tolerant measurement-based quantum computing (MBQC) system that includes multiple source modules operably connected to multiple optical circuits through multiple optical connections. The source modules are configured to generate resource states that are stitched together by the optical circuits to generate a higher-dimensional multimode entangled state. The source modules, optical circuits, and optical connections can be configured into repeatable tiles, where each tile comprises a subset of the source modules, optical circuits, and optical connections. The optical circuits are further configured to perform projective measurements on the multimode entangled state, such that a variety of quantum error correction codes may be implemented.

摘要： A method for simulation of a physical system such as a battery material, on a quantum computer and using ionic pseudopotentials, includes identifying, via a quantum computer, a ground state estimate for the physical system. A linear combination of unitaries (LCU) representing the physical system is received at the quantum computer, the LCU including a pseudopotential Hamiltonian term expressed as a sum of reflections. A qubitization of the pseudopotential Hamiltonian term is performed via the quantum computer based on (1) the LCU, (2) a first unitary operator configured to prepare a plurality of superpositions, and (3) a second unitary operator different from the first unitary operator, to produce a third unitary operator different from the first unitary operator and the second unitary operator. A quantum phase estimation is performed via the quantum computer based on the ground state estimate and the third unitary operator. The quantum phase estimation includes a set of at least one simulation, to identify a ground state energy estimate for the physical system.

摘要： A continuous system, process and associated apparatus are disclosed for reacting a gas with a liquid to manufacture a gaseous or liquid product. The preferred system comprises a reactive gas, such as chlorine and an aqueous solution, such as caustic soda, which are continuously combined and reacted under largely superatmospheric pressure and in turbulent cocurrent flow in very compact reactor equipment. Liquid bleach solutions such as aqueous solutions of hypochlorites or hypochlorous acid are among the products of major interest. The main reactor equipment consists of a fluid pressure energized, in-line mixing device followed by a low slip (closely fitted) regenerative turbine pumping unit. The fluid ports in the closely fitted stator elements of said pumping unit should have a radial dimension equal to at least about half that of the vanes. In a liquid ring compressor these ports are located adjacent the lower parts of said vanes while in a turbine pump they are generally adjacent the mid portion of said vanes.
