A 2048-spin bulk acoustic wave Ising machine for number partitioning and Sudoku
Summary
The arXiv paper proposes a 2048-spin bulk acoustic wave Ising machine that uses microwave delay lines to solve optimization tasks including number partitioning and Sudoku. It claims all-to-all connectivity with high thermal stability and shows competitive performance against simulated bifurcation methods, with potential scalability by using higher frequency delay lines.
