Landauer's principle
Appearance
English
[edit]Etymology
[edit]Named after German-American physicist Rolf Landauer (1927–1999), who proposed it in 1961.
Proper noun
[edit]- (physics, information theory) The principle that any logically irreversible manipulation of information must entail an increase in the entropy of the information-processing apparatus or its environment.

- Landauer's principle remained untested for over fifty years.

- Thus, the usual arguments for Landauer's Principle and reversible computing that do not address this case are overly simplistic; later, we will discuss how to generalize and repair them.
- 2022, Philipp Strasberg, Quantum Stochastic Thermodynamics, Oxford University Press, page 53:
- Equation (2.27) is often referred to as Landauer's principle.
In retrospect, one could object that Landauer's principle is a mere tautology. If one accepts the notion of Shannon entropy as non-equilibrium thermodynamic entropy, then Landauer's principle is nothing but the second law (2.24) of non-equilibrium thermodynamics applied to a special situation.
