Abstract: Methods, systems, and apparatus for enhanced decoding using in-phase and quadrature information. In one aspect, a method includes obtaining in-phase and quadrature values for multiple measurement operations in a quantum error correction code for a quantum computation; classifying measurement outcomes of the multiple measurement operations using respective in-phase and quadrature values; generating a detector graph of nodes and edges, wherein the detector graph labels detection events that occur in the classified measurement outcomes; assigning weights to the edges of the detector graph using posterior probability distributions of the classified measurement outcomes to generate a weighted detector graph; and executing a decoding process on the weighted detector graph to compute a decoding output of the decoding process, wherein the decoding output predicts an occurrence of errors in the quantum computation.

Abstract: A method for making a semiconductor device may include, in an epitaxial deposition tool, performing an anneal on a semiconductor on insulator (SOI) substrate including a first semiconductor layer, an insulating layer on the first semiconductor layer, and a second semiconductor layer on the insulating layer, the second semiconductor layer having a first thickness. The method may also include, in the epitaxial deposition tool, performing an in-situ etch to reduce the second semiconductor layer to a second thickness less than the first thickness, and forming a superlattice layer on the second semiconductor layer. The superlattice layer may include a plurality of stacked groups of layers, each group of layers comprising a plurality of stacked base semiconductor monolayers defining a base semiconductor portion, and at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base semiconductor portions.

Abstract: An image augmentation system and method for simulating the application of a coating to a surface of an original image. A mask generator can perform a search to detect a recognized object depicted in the original image, and generate a object mask for the recognized object. A user interface can to receive an identification of a selected object and an identification of a selected coating to be simulated on the selected object, and display a painted image. A renderer can receive the object mask for the selected object and the selected coating and generate the painted image, each pixel of the painted image having a painted color determined based on the object mask, the coating, and the original image.

Abstract: A method for recycling packaging wastes, referred to as first articles, made of PET or polyolefins (PO), that can be decolored in accordance with the “key-locker” principle, and second articles made of PET or PO, comprising the steps: (a) pre-sorting the first and second articles, (b) pre-washing the articles, (c) comminuting the articles to form flakes, (d) washing the articles, (e) dewatering and drying the flakes, (f) flake sorting, (g) extrusion, (h) solid-state polycondensation (SSP) in the case of PET wastes, or (i) decontamination in the case of PO wastes. The first articles are separated from the second articles by optical sorting and are decolored separate from the second articles in a decoloring step (j) by a reagent referred to as a “key.” The first decolored articles are temporarily stored (m) after step (j). After being stored, the first articles are fed to separate steps (g) and (h) or (i).

Abstract: A system, method and apparatus to label video images with assistance from an artificial neural network. After a user provides first inputs to label first aspects of an object shown in a first video frame, the artificial neural network infers or predicts second aspects to be labeled for the object in a second video frame. A graphical user interface presents the inferred or predicted second aspects over a display of the second video frame to allow the user to confirm or modify the inference or prediction. For example, an object of interest in the first frame can be labeled with a classification and a bounding box; and the artificial neural network is trained to infer or predict, for the corresponding object in the second frame, its bounding box, classification, and pixels represented of the image of the object in the second frame.

Abstract: Systems, devices, and methods related to a Deep Learning Accelerator and memory are described. For example, an integrated circuit device may be configured to execute instructions with matrix operands and configured with random access memory (RAM). A compiler has an artificial neural network configured to identify an optimized compilation option for an artificial neural network to be compiled by the compiler and/or for a hardware platform of Deep Learning Accelerators. The artificial neural network of the compiler can be trained via machine learning to identify the optimized compilation option based on the features of the artificial neural network to be compiled and/or features of the hardware platform on which the compiler output will be executed.
