A geometric Fano--Procrustes framework for purification-based distances and quantum channels analysis

Tristán M. Osán

In this work we reformulate the Uhlmann purification-overlap optimization and develop a purification-based geometric framework for the analysis of mixed qubit states and qubit chan…

A unified fidelity-based framework for quantum speed limits in open quantum systems

Tristán M. Osán, Yanet Álvarez, Mariela Portesi +1

In this work, we investigate the role of functionals of generalized fidelity measures in deriving quantum speed limits (QSLs) within a geometric approach. We establish a general th…

Behavior of quantum correlations under nondissipative decoherence by means of the correlation matrix

D. G. Bussandri, T. M. Osán, A. P. Majtey +1

In this paper we use the Fano representation of two-qubit states from which we can identify a correlation matrix containing the information about the classical and quantum correlat…

Geometric approach to extend Landau-Pollak uncertainty relations for positive operator-valued measures

G. M. Bosyk, S. Zozor, M. Portesi +2

We provide a twofold extension of Landau--Pollak uncertainty relations for mixed quantum states and for positive operator-valued measures, by recourse to geometric considerations.…

A geometric formulation of uncertainty principle

G. M. Bosyk, T. M. Osán, P. W. Lamberti +1

A geometric approach to formulate the uncertainty principle between quantum observables acting on an -dimensional Hilbert space is proposed. We consider the fidelity between a d…
