固有名詞

Landauer's principle

1. (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.
   • 2017, Momčilo Gavrilov, Experiments on the Thermodynamics of Information Processing, Springer, page 72,

     Landauer's principle remained untested for over fifty years.

   • 2018, Michael P. Frank, Physical Foundations of Landauer's Principle, Jarkko Kari, Irek Ulidowski (editors), Reversible Computation: 10th International Conference, Proceedings, Springer, LNCS, page 5,

     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.
