Is the focus on the erasure of a bit, rather than writing a bit, just conventional or is there a significant difference between the processes?
replyI'm not sure, but isn't 2 standard deviations a bit low? Especially so for something that can be done in a lab. It seems that 2 SD is the minimum threshold for getting published. Can we be sure that these are properly reviewed?
replyCould it be possible that you confused the number of standard deviations one needs to falsify something? For instance, if two things are different we may want to be as many SD as we can apart. Here, on the other hand, the data agree _within_ 2S D.
replyThat was the limit of just one experimental approach that was peer reviewed and published in a major journal. As you can see there are many experiments validating the limit and none invalidating it.
replyThe reality is that the Landauer limit is vanishingly small. I would encourage you to review the experiment methodology and see if you can come up with better, fundable methods.
