A combinatorial optimization problem (COP) is the problem of finding the optimal solution in
a finite set. When the size of the feasible solution set is large, the complexity of the problem …

We propose a spin-variable reduction method for Ising machines to handle linear equality
constraints in a combinatorial optimization problem. Ising machines including quantum …

We propose post-processing variational quantum algorithm (pVQA) for solving constrained
combinatorial optimization problems (COPs). COPs are typically transformed into ground …

In this article, we propose a postprocessing variationally scheduled quantum algorithm
(pVSQA) for solving constrained combinatorial optimization problems (COPs). COPs are …

As Moore's law approaches its inevitable end, the performance improvement of traditional
Von Neumann has encountered challenge. Some dedicated computing architecture for …
