Logical Entropy: Introduction to Classical and Quantum Logical Information Theory [PDF]
Entropy, 2018 Logical information theory is the quantitative version of the logic of partitions just as logical probability theory is the quantitative version of the dual Boolean logic of subsets.

Revisiting Entanglement within the Bohmian Approach to Quantum Mechanics [PDF]
Entropy, 2018 We revisit the concept of entanglement within the Bohmian approach to quantum mechanics. Inspired by Bohmian dynamics, we introduce two partial measures for the amount of entanglement corresponding to a pure state of a pair of quantum particles.

Entropic Steering Criteria: Applications to Bipartite and Tripartite Systems
Entropy, 2018 The effect of quantum steering describes a possible action at a distance via local measurements. Whereas many attempts on characterizing steerability have been pursued, answering the question as to whether a given state is steerable or not remains a ...

Measurement Uncertainty Relations for Position and Momentum: Relative Entropy Formulation [PDF]
Entropy, 2017 Heisenberg’s uncertainty principle has recently led to general measurement uncertainty relations for quantum systems: incompatible observables can be measured jointly or in sequence only with some unavoidable approximation, which can be quantified in ...

Alternative experimental ways to access entropy production
Physical Review Research, 2021 We theoretically derive and experimentally compare several different ways to access entropy production in a quantum process under feedback control. We focus on a bipartite quantum system realizing an autonomous Maxwell's demon scheme reported by Najera ...

Entropy Bounds for Multiparty Device-Independent Cryptography
PRX Quantum, 2021 Multiparty quantum cryptography based on distributed entanglement will find its natural application in the upcoming quantum networks. The security of many multipartite device-independent (DI) protocols, such as DI conference-key agreement, relies on ...

Non-Shannon inequalities in the entropy vector approach to causal structures [PDF]
Quantum, 2018 A causal structure is a relationship between observed variables that in general restricts the possible correlations between them. This relationship can be mediated by unobserved systems, modelled by random variables in the classical case or joint quantum

Introduction to logical entropy and its relationship to Shannon entropy
4 open, 2022 We live in the information age. Claude Shannon, as the father of the information age, gave us a theory of communications that quantified an “amount of information,” but, as he pointed out, “no concept of information itself was defined.” Logical entropy ...

Dilemma breaking in quantum games by joint probabilities approach
Scientific Reports, 2022 Classical games get fundamentally modified in the quantum realm because of non-locality and entanglement, that bypass some of the crucial features of the classical problem that define a dilemma.

Fundamental properties of Tsallis relative entropy [PDF]
, 2004 Fundamental properties for the Tsallis relative entropy in both classical and quantum systems are studied. As one of our main results, we give the parametric extension of the trace inequality between the quantum relative entropy and the minus of the ...
