Entropic uncertainty relations and their applications

PJ Coles, M Berta, M Tomamichel, S Wehner - Reviews of Modern Physics, 2017 - APS
Heisenberg's uncertainty principle forms a fundamental element of quantum mechanics.
Uncertainty relations in terms of entropies were initially proposed to deal with conceptual …

Strong majorization entropic uncertainty relations

Ł Rudnicki, Z Puchała, K Życzkowski - Physical Review A, 2014 - APS
We analyze entropic uncertainty relations in a finite-dimensional Hilbert space and derive
several strong bounds for the sum of two entropies obtained in projective measurements …

Entropic uncertainty from effective anticommutators

J Kaniewski, M Tomamichel, S Wehner - Physical Review A, 2014 - APS
We investigate entropic uncertainty relations for two or more binary measurements, for
example, spin-1 2 or polarization measurements. We argue that the effective …

Majorization approach to entropic uncertainty relations for coarse-grained observables

Ł Rudnicki - Physical Review A, 2015 - APS
We improve the entropic uncertainty relations for position and momentum coarse-grained
measurements. We derive the continuous, coarse-grained counterparts of the discrete …

A family of generalized quantum entropies: definition and properties

GM Bosyk, S Zozor, F Holik, M Portesi… - Quantum Information …, 2016 - Springer
We present a quantum version of the generalized (h, ϕ)(h, ϕ)-entropies, introduced by
Salicrú et al. for the study of classical probability distributions. We establish their basic …

General entropy-like uncertainty relations in finite dimensions

S Zozor, GM Bosyk, M Portesi - Journal of Physics A …, 2014 - iopscience.iop.org
We revisit entropic formulations of the uncertainty principle (UP) for an arbitrary pair of
positive operator-valued measures (POVM) A and B, acting on finite dimensional Hilbert …

Rényi, Shannon and Tsallis entropies of Rydberg hydrogenic systems

IV Toranzo, JS Dehesa - Europhysics Letters, 2016 - iopscience.iop.org
The Rényi entropies $ R_ {p}[\rho], 0< p<\infty $ of the probability density $\rho_ {n, l, m}(\vec
{r\,}) $ of a physical system completely characterize the chemical and physical properties of …

Certainty relations, mutual entanglement, and nondisplaceable manifolds

Z Puchała, Ł Rudnicki, K Chabuda, M Paraniak… - Physical Review A, 2015 - APS
We derive explicit bounds for the average entropy characterizing measurements of a pure
quantum state of size N in L orthogonal bases. Lower bounds lead to novel entropic …

Rényi formulation of uncertainty relations for POVMs assigned to a quantum design

AE Rastegin - Journal of Physics A: Mathematical and …, 2020 - iopscience.iop.org
Abstract Information entropies provide powerful and flexible way to express restrictions
imposed by the uncertainty principle. This approach seems to be very suitable in application …

[HTML][HTML] Highly symmetric POVMs and their informational power

W Słomczyński, A Szymusiak - Quantum Information Processing, 2016 - Springer
We discuss the dependence of the Shannon entropy of normalized finite rank-1 POVMs on
the choice of the input state, looking for the states that minimize this quantity. To distinguish …
