It's impossible to avoid incurring some losses at finite speed, but as far as I know there is nothing fundamental preventing one from approaching reversible operation when operating at a sufficiently slow (but nonzero) speed.

Sagawa was mistaken in this article; he failed to appreciate the role of mutual information in computing, which is the proper basis for understanding Landauer's principle. I discussed this in https://www.mdpi.com/1099-4

Thanks for the shout-out, Kragen! A more complete resource for finding my work count be found at https://revcomp.info .

Those can all be made reversible as well. :)

I believe it helps, because we don't have to reduce the bit energy as much to operate efficiently. But this would need to be studied in more detail.

I have concerns about density & cost for both photonic & superconductive computing. Not sure what one can do with quantum Hall effect. Regarding long-term returns, my view is that reversible computing is really the only way forward

Yeah, 2LAL (and its successor S2LAL) uses a very strict switching discipline to achieve truly, fully adiabatic switching. I haven't studied PFAL carefully but I doubt it's as good as 2LAL even in its more-adiabatic version. For a

It's been a while since I looked at it, but I believe PFAL is one of the not-fully-adiabatic techniques that I have a lot of critiques of. There have been studies showing that a truly, fully adiabatic technique in the sense I'm ta

There indeed has been research on reversible adiabatic logic in superconducting electronics. But superconducting electronics has a whole host of issues of its own, such as low density and a requirement for ultra-low temperatures. When I was

Hi, someone pointed me at your comment, so I thought I'd reply. First, the circuit techniques that aren't reversible aren't truly, fully adiabatic either -- they're only quasi-adiabatic. In fact, if you strictly follow t

Thanks for the plug! :D
