Is that reversible or reversibly-knotted or? > "The thermodynamic meaning of negative entropy" (2011) https://www.nature.com/articles/nature10123 https://www.nature.com/articles/nature10123 Though also Landauer's limit presumably only applies to electrons; not photons or phonons or gravitational waves.
