Group-invariant estimation of symmetric states generated by noisy quantum computers
Federico Holik, Marcelo Losada, Giannina Zerr +2
The problem of quantum state estimation is crucial in the development of quantum technologies. In particular, the use of symmetric quantum states is useful in many relevant applica…
Segmentation of quantum generated sequences by using the Jensen-Shannon divergence
Marcelo Losada, Víctor A. Penas, Federico Holik +1
The Jensen-Shannon divergence has been successfully applied as a segmentation tool for symbolic sequences, that is to separate the sequence into subsequences with the same symbolic…
Parameterizing density operators with arbitrary symmetries to gain advantage in quantum state estimation
Inés Corte, Marcelo Losada, Diego Tielas +2
In this work, we show how to parameterize a density matrix that has an arbitrary symmetry, knowing the generators of the Lie algebra (if the symmetry group is a connected Lie group…
Quantum identity, content, and context: from classical to non-classical logic
J. Acacio de Barros, Federico Holik, Décio Krause
In this paper, we discuss content and context for quantum properties. We give some examples of why quantum properties are problematic: they depend on the context in a non-trivial w…
Quantum State Discrimination for Supervised Classification
Roberto Giuntini, Hector Freytes, Daniel K. Park +4
In this paper we investigate the connection between quantum information theory and machine learning. In particular, we show how quantum state discrimination can represent a useful…
On the assumptions underlying KS-like contradictions
J. Acacio de Barros, Juan Pablo Jorge, Federico Holik
The Kochen-Specker theorem is one of the fundamental no-go theorems in quantum theory. It has far-reaching consequences for all attempts trying to give an interpretation of the qua…
Indistinguishability and Negative Probabilities
J. Acacio de Barros, Federico Holik
In this paper, we examined the connection between quantum systems' indistinguishability and signed (or negative) probabilities. We do so by first introducing a measure-theoretic de…
Extremal elements of a sublattice of the majorization lattice and approximate majorization
César Massri, Guido Bellomo, Federico Holik +1
Given a probability vector with its components sorted in non-increasing order, we consider the closed ball with formed by the probability vect…
Indistinguishability and the origins of contextuality in physics
José Acacio de Barros, Federico Holik, Décio Krause
In this work we discuss a formal way of dealing with properties of contextual systems. Our approach is to assume that properties describing the same physical quantity, but belongin…
Evolution of quantum observables: from non-commutativity to commutativity
Sebastian Fortin, Manuel Gadella, Federico Holik +1
A fundamental aspect of the quantum-to-classical limit is the transition from a non-commutative algebra of observables to commutative one. However, this transition is not possible…
Non-deterministic semantics for quantum states
Juan Pablo Jorge, Federico Holik
In this work we discuss the failure of the principle of truth functionality in the quantum formalism. By exploiting this failure, we import the formalism of N-matrix theory and non…
Optimal common resource in majorization-based resource theories
G. M. Bosyk, G. Bellomo, F. Holik +2
We address the problem of finding the optimal common resource for an arbitrary family of target states in quantum resource theories based on majorization, that is, theories whose c…
Hermite-Gaussian model for quantum states
Marcelo Losada, Ignacio S. Gomez, Federico Holik
In order to characterize quantum states within the context of information geometry, we propose a generalization of the Gaussian model, which we called the Hermite-Gaussian model. W…
Logical structures underlying quantum computing
Federico Holik, Giuseppe Sergioli, Hector Freytes +1
In this work we advance a generalization of quantum computational logics capable of dealing with some important examples of quantum algorithms. We outline an algebraic axiomatizati…

Marcelo Losada, Federico Holik, Cesar Massri +1
We present a system of equations and an explicit solution for the problem of determining the MaxEnt state of a quantum system satisfying symmetry constraints.
Dynamics of algebras in quantum unstable systems
Marcelo Losada, Sebastian Fortin, Manuel Gadella +1
We introduce a dynamical evolution operator for dealing with unstable physical process, such as scattering resonances, photon emission, decoherence and particle decay. With that ai…
Generalized entropies in quantum and classical statistical theories

We study a version of the generalized (h, ϕ)-entropies, introduced by Salicrú et al, for a wide family of probabilistic models that includes quantum and classical statistical theor…
Lossless quantum data compression with exponential penalization: an operational interpretation of the quantum Rényi entropy
G. Bellomo, G. M. Bosyk, F. Holik +1
Based on the problem of quantum data compression in a lossless way, we present here an operational interpretation for the family of quantum Rényi entropies. In order to do this, we…
Contextuality and Indistinguishability
J. Acacio de Barros, Federico Holik, Decio Krause
It is well known that in quantum mechanics we cannot always define consistently properties that are context independent. Many approaches exist to describe contextual properties, su…

C. Massri, F. Holik
In this paper we investigate measures over bounded lattices, extending and giving a unifying treatment to previous works. In particular, we prove that the measures of an arbitrary…
