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…
Performance of the quantum MaxEnt estimation in the presence of physical symmetries
Diego Tielas, Marcelo Losada, Lorena Rebón +1
When an informationally complete measurement is not available, the reconstruction of the density operator that describes the state of a quantum system can be accomplish, in a relia…
Gamow vectors formalism applied to the Loschmidt echo
Sebastian Fortin, Manuel Gadella, Federico Holik +1
Gamow vectors have been developed in order to give a mathematical description for quantum decay phenomena. Mainly, they have been applied to radioactive phenomena, scattering and t…
Generalized coherence vector applied to coherence transformations and quantifiers
G. M. Bosyk, M. Losada, C. Massri +2
One of the main problems in any quantum resource theory is the characterization of the conversions between resources by means of the free operations of the theory. In this work, we…
Frauchiger-Renner argument and quantum histories
Marcelo Losada, Roberto Laura, Olimpia Lombardi
In this article we reconstruct the Frauchiger and Renner argument, taking into account that the assertions of the argument are made at different times. To do this, we use a formali…
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…
Solutions for the MaxEnt problem with symmetry constraints
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…
Quantum histories without contrary inferences
Marcelo Losada, Roberto Laura
In the consistent histories formulation of quantum theory it was shown that it is possible to retrodict contrary properties. We show that this problem do not appear in our formalis…
A semiclassical condition for chaos based on Pesin theorem
Ignacio Gomez, Marcelo Losada, Sebastian Fortin +2
A semiclassical method to determine if the classical limit of a quantum system is chaotic or not, based on Pesin theorem, is presented. The method is applied to a phenomenological…
