That sounds similar to this in QC:

From "Reversible computing escapes the lab" (2025) https://news.ycombinator.com/item?id=42660606#42705562 :

> FWIU from "Quantum knowledge cools computers", if the deleted data is still known, deleting bits can effectively thermally cool, bypassing the Landauer limit of electronic computers? Is that reversible or reversibly-knotted or?

> "The thermodynamic meaning of negative entropy" (2011) https://www.nature.com/articles/nature10123

Though also Landauer's limit presumably only applies to electrons; not photons or phonons or gravitational waves.

Can you feed gravitationaly waves forward to a receptor that only carries that gravitational waves bit, but can be recalled?
