Thermodynamics of chemical computing.

[Rory Brittain @RoryABrittain]

@gravity_levity I the past I had a lot of trouble with R because the function to make a vector is just 'c'.

[Systems and Signals @sys_sig]

A new paper with Rory Brittain and Tom Ouldridge:
What would it take to build a thermodynamically reversible Universal Turing machine?

We find a link between halting and energetic cost.

@TheMattGarry Thanks. I was surprised you and Sarab weren't on the list. Did you not make the cut-off date for this year?

[Rory Brittain @RoryABrittain]

Officially graduating (virtually) today. #OurImperial

[Rory Brittain @RoryABrittain]

This week I'm (virtually) attending DNA 26.

I'm currently looking for a job.

This paper was from a couple of years ago and I think there has been quite a bit of other work on speed limits in the mean time.

A similar result is used in this paper:

Recently I've been reading 'Speed Limit for Classical Stochastic Processes' by Shiraishi, Funo and Saito.

You could then look at modifying the process to increase the efficiency. However, in modifying the process the activity also, in general, changes so the lower bound changes.

My thesis has finally been added to the Imperial College London repository:

This is important for chemical computing because you can't do a computation if your output species are independent of your input species.

[Rory Brittain @RoryABrittain]

A fact about chemical reaction networks that I learnt from https://t.co/efR9ZJvUoD (arXiv: https://t.co/IzhgJa2yP0). For a detailed-balanced network the steady state distribution is a product of Poisson distributions restricted to the reachability class.

[Rory Brittain @RoryABrittain]

This means that if we want the distributions for different species to not independent either the system must be out of equilibrium or the reachability class must be restricted by a conservation law.
