What would it take to build a thermodynamically reversible Universal Turing machine? Computational and thermodynamic constraints in a molecular design
Rory A. Brittain, Nick S. Jones, Thomas E. Ouldridge
We outline the construction of a molecular system that could, in principle, implement a thermodynamically reversible Universal Turing Machine (UTM). By proposing a concrete-albeit…

The power of being explicit: demystifying work, heat, and free energy in the physics of computation
Thomas E Ouldridge, Rory A. Brittain, Pieter Rein ten Wolde
Interest in the thermodynamics of computation has revived in recent years, driven by developments in science, economics and technology. Given the consequences of the growing demand…

Biochemical Szilard engines for memory-limited inference
Rory A. Brittain, Nick S. Jones, Thomas E. Ouldridge
By developing and leveraging an explicit molecular realisation of a measurement-and-feedback-powered Szilard engine, we investigate the extraction of work from complex environments…
