Certainty relations, mutual entanglement and non-displacable manifolds
Zbigniew Puchała, Łukasz Rudnicki, Krzysztof Chabuda +2
We derive explicit bounds for the average entropy characterizing measurements of a pure quantum state of size in orthogonal bases. Lower bounds lead to novel entropic uncer…
Distinguishability of generic quantum states
Zbigniew Puchała, Łukasz Pawela, Karol Życzkowski
Properties of random mixed states of order distributed uniformly with respect to the Hilbert-Schmidt measure are investigated. We show that for large , due to the concentrat…
Minimal Renyi-Ingarden-Urbanik entropy of multipartite quantum states
Marco Enriquez, Zbigniew Puchała, Karol Życzkowski
We study the entanglement of a pure state of a composite quantum system consisting of several subsystems with levels each. It can be described by the Rényi-Ingarden-Urbanik ent…
Exploring boundaries of quantum convex structures: special role of unitary processes
Zbigniew Puchała, Anna Jencova, Michal Sedlak +1
We address the question of finding the most effective convex decompositions into boundary elements (so-called boundariness) for sets of quantum states, observables and channels. Fi…
