Optimal quantum teleportation protocols for fixed average fidelity
Fabricio Toscano, Diego G. Bussandri, Gustavo M. Bosyk +2
We demonstrate that among all quantum teleportation protocols giving rise to the same average fidelity, those with aligned Bloch vectors between input and output states exhibit the…
Revisiting maximal average fidelity of teleportation
D. G. Bussandri, M. Portesi, A. P. Majtey
We obtain the maximal average fidelity corresponding to the standard quantum teleportation protocol for an arbitrary isotropic distribution of input states and an arbitrary resourc…
Fluctuation and dissipation in memoryless open quantum evolutions
Fabricio Toscano, Gustavo M. Bosyk, Steeve Zozor +1
Von Neumann entropy rate for open quantum systems is, in general, written in terms of entropy production and entropy flow rates, encompassing the second law of thermodynamics. When…
-Deformed quantum and classical mechanics for a system with position-dependent effective mass
Bruno G. da Costa, Ignacio S. Gomez, Mariela Portesi
We present the quantum and classical mechanics formalisms for a particle with position-dependent mass in the context of a deformed algebraic structure (named -algebra), motivate…
Entropic analysis of the quantum oscillator with a minimal length
David Puertas Centeno, Mariela Portesi
The well-known Heisenberg--Robertson uncertainty relation for a pair of noncommuting observables, is expressed in terms of the product of variances and the commutator among the ope…
Fisher metric from relative entropy group
Ignacio S. Gomez, Ernesto P. Borges, M. Portesi
In this work we consider the Fisher metric which results from the Hessian of the relative entropy group, that we called Fisher metric group, and we obtain the corresponding ones to…
