Characterization of equivariant maps and application to entanglement detection
Ivan Bardet, Benoît Collins, Gunjan Sapra
We study equivariant linear maps between finite-dimensional matrix algebras, as introduced by Bhat. These maps satisfy an algebraic property which makes it easy to study their posi…
Recurrence and transience of continuous-time open quantum walks
Ivan Bardet, Hugo Bringuier, Yan Pautrat +1
This paper is devoted to the study of continuous-time processes known as continuous-time open quantum walks (CTOQWs). A CTOQW represents the evolution of a quantum particle constra…
Hypercontractivity and logarithmic Sobolev Inequality for non-primitive quantum Markov semigroups and estimation of decoherence rates
Ivan Bardet, Cambyse Rouzé
We generalize the concepts of weak quantum logarithmic Sobolev inequality (LSI) and weak hypercontractivity (HC), introduced in the quantum setting by Olkiewicz and Zegarlinski, to…
de Finetti reductions for partially exchangeable probability distributions
Ivan Bardet, Cécilia Lancien, Ion Nechita
We introduce a general framework for de Finetti reduction results, applicable to various notions of partially exchangeable probability distributions. Explicit statements are derive…
