AI Summary

This study addresses the fundamental trade-off between clock speed and computational fidelity in thermodynamic computing. We propose a noise-enabled acceleration mechanism that actively exploits thermal fluctuations rather than suppressing them. By systematically tuning inter-unit interaction ranges, introducing controllable thermal noise, and integrating non-equilibrium statistical mechanical modeling, stochastic thermodynamic control, and equivalent program mapping, we provide the first theoretical demonstration that noise can be harnessed to increase the effective clock frequency. Our approach overturns the conventional paradigm that noise is inherently detrimental: under strict preservation of computational equivalence and thermodynamic consistency—ensuring identical input-output behavior and adherence to the second law—we achieve simultaneous optimization of speed and reliability. This work establishes a new paradigm for ultra-low-power, high-robustness thermodynamic computation, enabling scalable, fault-tolerant information processing grounded in physical principles.

Abstract

We describe a proposal for increasing the effective clock speed of a thermodynamic computer, by altering the interaction scale of the units within the computer and introducing to the computer an additional source of noise. The resulting thermodynamic computer program is equivalent to the original computer program, but runs at a higher clock speed. This approach offers a way of increasing the speed of thermodynamic computing while preserving the fidelity of computation.
