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…
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…
Chemical Boltzmann Machines
William Poole, Andrés Ortiz-Muñoz, Abhishek Behera +4
How smart can a micron-sized bag of chemicals be? How can an artificial or real cell make inferences about its environment? From which kinds of probability distributions can chemic…
What we learn from the learning rate
Rory A. Brittain, Nick S. Jones, Thomas E. Ouldridge
The learning rate is an information-theoretical quantity for bipartite Markov chains describing two coupled subsystems. It is defined as the rate at which transitions in the downst…
Designing the Optimal Bit: Balancing Energetic Cost, Speed and Reliability
Abhishek Deshpande, Manoj Gopalkrishnan, Thomas E. Ouldridge +1
We consider the technologically relevant costs of operating a reliable bit that can be erased rapidly. We find that both erasing and reliability times are non-monotonic in the unde…
Generalized Methods and Solvers for Noise Removal from Piecewise Constant Signals
Max A. Little, Nick S. Jones
Removing noise from piecewise constant (PWC) signals, is a challenging signal processing problem arising in many practical contexts. For example, in exploration geosciences, noisy…
