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.
New research demonstrates that silicon oscillators can solve complex computational problems exponentially faster than traditional semiconductor-based digital computers.
This article details the electromechanical Angle Computer used in the B-52 bomber's Astro Compass celestial navigation system, which automatically tracked stars and performed trigonometric calculations to enable accurate heading and position determination before the era of GPS.
