Abstract: We use a gradient-based optimization scheme to find single-qubit rotations to be interwoven between time steps of a noisy logical two-qubit entangling gate in order to suppress the effects of arbitrary logical and leakage noise…

Abstract: This letter introduces a novel grayscale-inversion and rotation invariant descriptor, called sorted local gradient pattern, for texture classification. First, we propose two complementary local gradient patterns (LGP), the center-to-ring LGP (LGP_CR) and the ring-to-ring LGP…

Abstract: Local descriptors used in face recognition are robust in a sense that these descriptors perform well in varying pose, illumination, and lighting conditions. The accuracy of these descriptors depends on the precision of mapping the…
