Unifying computational entropies via Kullback-Leibler divergence
one-way functions pseudo-randomness bit commitment
2019/3/6
We introduce KL-hardness, a new notion of hardness for search problems which on the one hand is satisfied by all one-way functions and on the other hand implies both next-block pseudoentropy and inacc...
On Renyi Entropies and their Applications to Guessing Attacks in Cryptography
brute force guessing attacks predictability entropy
2018/5/22
We consider single and multiple attacker scenarios in guessing and obtain bounds on various success parameters in terms of Renyi entropies. We also obtain a new derivation of the union bound.
Clausius versus Sackur-Tetrode entropies
Clasius (thermodynamical)/statistical entropy Gibbs paradox extensivity thermodynamic limit
2016/6/15
Based on the property of extensivity (mathematically, homogeneity of first degree), we derive in a mathematically consistent manner the explicit expressions of the chemical potential and the Clausius ...
Nonconcave entropies from generalized canonical ensembles
Microcanonical ensemble entropy the curies - Weiss - Potts spin model model
2014/12/25
It is well known that the entropy of the microcanonical ensemble cannot be calculated as the Legendre transform of the canonical free energy when the entropy is nonconcave. To circumvent this problem,...
Critical entropies for magnetic ordering in bosonic mixtures on a lattice
Simulation worm algorithm 3 d optical lattice temperature system antiferromagnetic particles
2014/12/18
We perform a numeric study (Worm algorithm Monte Carlo simulations) of ultracold two-component bosons in two- and three-dimensional optical lattices. At strong enough interactions and low enough tempe...

GENERALIZED RELATIVE ENTROPIES STOCHASTIC REPRESENTATION
2014/4/4
We provide a stochastic interpretation of a result of decay of generalized relative entropies that was discovered by Michel,Mischler and Perthame.
Information Theoretic Security for Encryption Based on Conditional Renyi Entropies
Impossibility Symmetric-key Encryption
2014/3/11
In this paper, information theoretic cryptography is discussed based on conditional Renyi entropies. Our discussion focuses not only on cryptography but also on the de nitions of conditional Renyi e...
On some interrelations of generalized $q$-entropies and a generalized Fisher information, including a Cramér-Rao inequality
Cramér-Rao inequality generalizedq-entropy generalized Gaussians de Bruijn identity
2013/6/17
In this communication, we describe some interrelations between generalized $q$-entropies and a generalized version of Fisher information. In information theory, the de Bruijn identity links the Fisher...
The general form of gamma-family of quantum relative entropies
gamma-family quantum relative entropies Falcone-Takesaki non-commutative flow
2011/7/27
Abstract: We use the Falcone-Takesaki non-commutative flow of weights and the resulting theory of non-commutative Lp spaces in order to define the family of relative entropy functionals that naturally...

Topological entropies Measure-theoretical entropies
2011/1/18
Let (X, T ) be a topological dynamical system. We define the measure-theoretical lower and upper entropies hμ(T ), hμ(T ) for any μ ∈ M(X), where M(X) denotes the collection of all Borel probability m...

Fano inequality Tsallis q-entropy relative q-entropy entanglement fidelity
2010/11/4
Generalizations of the quantum Fano inequality are considered. The notion of $q$-entropy exchange is introduced. This quantity is concave in each of its two arguments. For $q\geq0$, the inequality of ...
Uncertainty relations give upper bounds on the accuracy by which the outcomes of two incompatible measurements can be predicted. While the established uncertainty relations apply to cases where the pr...

Generalized-generalized entropies and limit distributions
Limit distributions Correlated random numbers Entropy for arbitrary distributions
2010/7/5
Limit distributions are not limited to uncorrelated variables but can be constructively derived for a large class of correlated random variables, as was shown e.g. in the context of large deviation th...

q-Entropies Entanglement dynamics
2010/7/5
We investigate entropic aspects of the quantum entanglement dynamics of two-qubits systems interacting with an environment. In particular we consider the detection, based on the violation of classical...
