Landauer's principle

English Etymology Named after German-American physicist Rolf Landauer (1927–1999), who proposed it in 1961. Proper noun en 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. en 2017 Momčilo Gavrilov Experiments on the Thermodynamics of Information Processing https://books.google.com.au/books?id=fR8vDwAAQBAJ&pg=PA72&dq=%22Landauer+principle%22%7C%22Landauer%27s+principle%22&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwi1_YG_jcb9AhXGSvEDHSAfDqkQ6AF6BAhiEAI#v=onepage&q=%22Landauer%20principle%22%7C%22Landauer's%20principle%22&f=false 72 Springer 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, Lecture Notes in Computer Science 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. en 2022 Philipp Strasberg Quantum Stochastic Thermodynamics https://books.google.com.au/books?id=ryRXEAAAQBAJ&pg=PA53&dq=%22Landauer+principle%22%7C%22Landauer%27s+principle%22&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwi1_YG_jcb9AhXGSvEDHSAfDqkQ6AF6BAhcEAI#v=onepage&q=%22Landauer%20principle%22%7C%22Landauer's%20principle%22&f=false 53 w:Oxford University Press 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.
