Reducing qubit energy decay and correlated errors from cosmic rays in quantum processors
Large algorithms can be run on a quantum computer only if quantum error correction is used to lower logical qubit errors. The energy deposited by cosmic-ray muons produces a quasiparticle “heat” pulse that causes the qubits to decay in energy quickly, with errors correlated in space and time, so that error correction fails. Metal layers comprising normal metal and/or small-gap superconductors channel this energy away from the qubit into benign structures so that qubit performance is not degraded. These structures are designed according to the electron-phonon interactions and constraints from electromagnetic radiation to make large reductions in the induced errors so that error correction works properly. |

System and method for digital image intensity correction
The present invention provides a method, system and image to enhance the image contrast of a digital image device while simultaneously compensating for image intensity inhomogeneity, regardless of the source. The present invention corrects intensity inhomogeneities producing a more uniform image appearance. Also, the image is enhanced through increased contrast, e.g., tissue contrast in a medical image. The method makes no assumptions as to the source of the inhomogeneities, e.g., physical device characteristics or positioning of the object being imaged. In the method, the error between the histogram of the spatially-weighted original image and a specified histogram is minimized. The specified histogram may be selected to increase contrast generally or particularly for accentuation, e.g., on localized regions of interest. The weighting is preferably achieved by two-dimensional interpolation of a sparse grid of control points overlaying the image. A sparse grid is used rather than a dense one to compensate for slowly-varying image non-uniformity. Also, sparseness reduces the computational complexity, as the final weight set involves the solution of simultaneous linear equations whose number is the size of the chosen grid. |

Method and system for image segmentation and identification
An image segmentation method system, the system comprising: a training subsystem configured to train a segmentation machine learning model using annotated training data comprising images associated with respective segmentation annotations, so as to generate a trained segmentation machine learning model; a model evaluator; and a segmentation subsystem configured to perform segmentation of a structure or material in an image using the trained segmentation machine learning model. The model evaluator is configured to evaluate the segmentation machine learning model by (i) controlling the segmentation subsystem to segment at least one evaluation image associated with an existing segmentation annotation using the segmentation machine learning model and thereby generate a segmentation of the annotated evaluation image, and (ii) forming a comparison of the segmentation of the annotated evaluation image and the existing segmentation annotation. The method includes deploying the trained segmentation machine learning model for use if the comparison indicates that the segmentation machine learning model is satisfactory. |
