Hi, not to spend a lot of time here, but someone called my attention to the fact that I was mentioned in the comments. Just a few things:
In the comment of mine where I was quoted, I was talking about conventional architectures wherein one erases bits by simply discarding the signal energy, and where the signals themselves have enough associated energy (e.g. an energy difference between 0 and 1 states, or an energy barrier between the states) to be reliably distinguished despite thermal noise. Yes, theoretically one can do somewhat better than this (i.e., closer to the kT ln 2 minimum) with more complicated erasure protocols, but these do generally come at
