Quantum Conditional Logical Entropy of Dynamical Systems
In this paper, we will define the notion of conditional logical entropy of dynamical systems on a quantum logic. We will prove some of its properties. The relation between this measure and the notion of logical entropy of quantum dynamical systems which was defined in my paper (Open Physics, 14:1-5, 2016), will be presented.
متن کاملThe conditional Entropy Power Inequality for bosonic quantum systems
We prove the conditional Entropy Power Inequality for Gaussian quantum systems. This fundamental inequality determines the minimum quantum conditional von Neumann entropy of the output of the beam-splitter or of the squeezing among all the input states where the two inputs are conditionally independent given the memory and have given quantum conditional entropies. We also prove that, for any co...
متن کاملGeneralized entropy production fluctuation theorems for quantum systems
Based on trajectory dependent path probability formalism in state space, we derive generalized entropy production fluctuation relations for a quantum system in the presence of measurement and feedback. We have obtained these results for three different cases: (i) the system is evolving in isolation from its surroundings; (ii) the system being weakly coupled to a heat bath; and (iii) system in c...
متن کاملTsallis Entropy and Conditional Tsallis Entropy of Fuzzy Partitions
The purpose of this study is to define the concepts of Tsallis entropy and conditional Tsallis entropy of fuzzy partitions and to obtain some results concerning this kind entropy. We show that the Tsallis entropy of fuzzy partitions has the subadditivity and concavity properties. We study this information measure under the refinement and zero mode subset relations. We check the chain rules for ...
متن کاملAntilinearity in Bipartite Quantum Systems and Teleportation
In this paper I consider some assorted antilinear operations and operators in bipartite quantum systems, an application to quantum teleportation, and a link to Tomita and Takasaki’s theory via twisted direct products. The idea is in exploring the natural antilinearity which is inherent to vectors in direct products of Hilbert spaces. The reason for the appearance of certain antilinear maps, her...
