  • Publication number: 20240133987
    Abstract: A system and method for L0 regularization-based compressed sensing (CS) may use a quantum-classical hybrid system consisting of coherent Ising machines (CIM) and classical digital processors CDP). The CIM and CDP each performs alternating minimization for L0 regularization-based compressed sensing (CS). A truncated Wigner stochastic differential equation (W-SDE) is obtained from the master equation for the density operator of the network of degenerate optical parametric oscillators.

  • Publication number: 20240100635
    Abstract: A core material has a core 12; a solder layer 16 made of a (Sn—Bi)-based solder alloy provided on an outer side of the core 12; and a Sn layer 20 provided on an outer side of the solder layer 16. The core contains metal or a resin. When a concentration ratio of Bi contained in the solder layer 16 is a concentration ratio (%)=a measured value of Bi (% by mass)/a target Bi content (% by mass), or a concentration ratio (%)=an average value of measured values of Bi (% by mass)/a target Bi content (% by mass), the concentration ratio is 91.4% to 106.7%. The thickness of the Sn layer 20 is 0.215% or more and 36% or less of the thickness of the solder layer 16.
