We discuss the relationship between entropic uncertainty relations and entanglement. We present two methods for deriving separability criteria in terms of entropic uncertainty relations. In particular, we show how any entropic uncertainty relation on one part of the system results in a separability condition on the composite system. We investigate the resulting criteria using the Tsallis entropy for two and three qubits. 
Entanglement criteria from multiple observables entropic uncertainty relations
We investigate quantum entanglement for both bipartite and multipartite systems by using entropic uncertainty relations (EUR) defined in terms of the joint Shannon entropy of probabilities of local
Entropic uncertainty relations and the stabilizer formalism
Entropic uncertainty relations express the quantum mechanical uncertainty principle by quantifying uncertainty in terms of entropy. Central questions include the derivation of lower bounds on the
Entanglement Detection via Direct-Sum Majorization Uncertainty Relations
The primary results are entanglement detection methods based on direct-sum majorization uncertainty relations that provide a set of sufficient conditions for detectingEntanglement whose number grows linearly with the dimension of the state being detected.
Entropic Uncertainty Relations in Quantum Physics
Uncertainty relations have become the trademark of quantum theory since they were formulated by Bohr and Heisenberg. This review covers various generalizations and extensions of the uncertainty

Entanglement criteria via concave-function uncertainty relations
A general theorem as a necessary condition for the separability of quantum states in both finite and infinite dimensional systems, based on concave-function uncertainty relations, is derived. Two
Collision entropy and optimal uncertainty
We propose an alternative measure of quantum uncertainty for pairs of arbitrary observables in the two-dimensional case, in terms of collision entropies. We derive the optimal lower bound for this
Improved bounds on entropic uncertainty relations
A novel lower bound on the entropy sum for general pairs of observables in finite-dimensional Hilbert space is obtained, which improves on the best bound known to date.
Uncertainty relations and entanglement in fermion systems
The violation of uncertainty relations is used as a signature of entanglement for both pure and mixed states of two identical fermions. In the case of fermions with a four-dimensional single-particle
Entanglement and discord assisted entropic uncertainty relations under decoherence
The uncertainty principle is a crucial aspect of quantum mechanics. It has been shown that quantum entanglement as well as more general notions of correlations, such as quantum discord, can relax or


Conditional entropies and their relation to entanglement criteria
It is shown that any state having a negative conditional entropy with respect to any value of the entropic parameter is distillable since it violates the reduction criterion.
Separability conditions from entropic uncertainty relations
We derive a collection of separability conditions for bipartite systems of dimension dxd which is based on the entropic version of the uncertainty relations. A detailed analysis of the two-qubit case

A family of necessary separability criteria for finite-dimensional systems is derived based on inequalities for variances of observables based on covariance matrices and it is shown that every pure bipartite entangled state violates some of these inequalities.
Violation of local uncertainty relations as a signature of entanglement
Entangled states represent correlations between two separate systems that are too precise to be represented by products of local quantum states. We show that this limit of precision for the local
Generalized nonadditive entropies and quantum entanglement.
The inference of quantum density operators from incomplete information by means of the maximization of general nonadditive entropic forms allows one to avoid fake entanglement for data based on the Bell-Clauser-Horne-Shimony-Holt observable, and, in general, on any set of Bell constraints.
Generalized entropic uncertainty relations.
A new class of uncertainty relations is derived for pairs of observables in a finite-dimensional Hilbert space which do not have any common eigenvector. This class contains an ``entropic''
Uncertainty relations for information entropy in wave mechanics
New uncertainty relations in quantum mechanics are derived. They express restrictions imposed by quantum theory on probability distributions of canonically conjugate variables in terms of
