Mutual Entropy-Production and Sensing in Bipartite Systems

Understand

We introduce and analyze the notion of mutual entropy-production (MEP) in autonomous systems.

• Evaluating MEP rates is in general a difficult task due to non-Markovian effects.
• For bipartite systems, we provide closed expressions in various limiting regimes which we verify using numerical simulations.
• Based on the study of a biochemical and an electronic sensing model, we suggest that the MEP rates provide a relevant measure of the accuracy of sensing.
