Thomas Kehrenberg comments on Deconfusing Landauer’s Principle

[Thomas Kehrenberg]

Great article! It clarified the concepts a lot for me.

therefore by eq. 1 we get $\Delta H\left(X|C\right)\ge -H\left(C\right)=+1$.

I think you’re missing a $\Delta$ in front of the $H\left(C\right)$ here. (Entropy cannot be negative.)

Fixed, thanks!
