This paper presents a 2048-spin bulk acoustic wave Ising machine using microwave delay lines, achieving all-to-all connectivity and solving MAX-CUT, number partitioning, and Sudoku problems with higher thermal stability and performance compared to state-of-the-art coherent Ising machines.
This paper presents a programmable probabilistic computer with one million p-bits by networking FPGAs, achieving Gibbs sampling at over a trillion flips per second for Ising models while introducing a design rule for scaling beyond single-chip limits.
