Biggest Probabilistic Computer Turns Noise Into Answers with One Million P-Bits

Biggest Probabilistic Computer Turns Noise into Answers

I explore how a new machine built from 18 FPGAs creates the largest probabilistic computer yet, featuring one million p-bits. This breakthrough solves complex optimization problems by harnessing correlated noise rather than avoiding it. Unlike quantum computers, this programmable system scales effectively across multiple chips without needing global synchronization, paving the way for arbitrarily large machines that tackle stochastic challenges standard computers cannot.

"Systems combining CMOS with dense stochastic memory technologies such as MRAM offer one of the most compelling paths forward."
