Title:
イジングモデルの計算装置
Document Type and Number:
Japanese Patent JP6734997
Kind Code:
B2
Abstract:
The evaluation index of a calculation accuracy of an Ising model calculation device is provided independent of an inputted problem. This allows the Ising model calculation device to select a solution having a consistent quality from among solutions obtained through the calculations to output the selected solution. A coupling coefficient obtained by combining the Ising model coupling coefficient corresponding to a problem for which a solution should be calculated with the Ising model coupling coefficient corresponding to the check problem is set as a coupling coefficient used to calculate the interaction. With regard to a calculation value corresponding to the check spin among the calculation values using a plurality of light pulses, the compatibility as the solution of the check problem is judged. When the judgement result shows the compatibility as the solution of the check problem, a calculation value other than the calculation values corresponding to the check spin among the resultant calculation values is outputted as a solution to the problem for which a solution should be calculated.
