For a decade, the promise of probabilistic computing has been overshadowed by a single, physical bottleneck: the need for bulky, power-draining analog control circuits. This technology relies on hardware elements, called p-bits, that naturally fluctuate between 'one' and 'zero,' allowing systems to efficiently solve optimization and inference problems that baffle traditional computers. Yet, to fine-tune that chaotic flipping, p-bit designs have required a component known as a Digital-to-Analog Converter (DAC).
