Shannon's entropy

Webb27 maj 2024 · Keywords: complex systems; nonadditive entropies; nonextensive statistical mechanics; beyond Boltzmann–Gibbs–Shannon. An entropic functional S is said additive if it satisfies, for any two probabilistically independent systems A and B, that . If not, it is said nonadditive. In the literature, since the pioneering works of Boltzmann (1872 ... WebbTools. In probability theory and statistics, the Jensen – Shannon divergence is a method of measuring the similarity between two probability distributions. It is also known as information radius ( IRad) [1] [2] or total divergence to the average. [3] It is based on the Kullback–Leibler divergence, with some notable (and useful) differences ...

Webb11 apr. 2024 · Abstract. The statistics of work done on a quantum system can be quantified by the two-point measurement scheme. We show how the Shannon entropy of the work distribution admits a general upper bound depending on the initial diagonal entropy, and a purely quantum term associated to the relative entropy of coherence.
