Fisher information and quantum systems with position-dependent effective mass
(Elsevier Science, 2000-03)
We show that effective masses in nonrelativistic quantum mechanics arise in a natural fashion from the Frieden and Soffer's Principle of Extremal Information (EPI) when the mean values of operators involving the momentum ...
Entanglement, decoherence and estimation in neutrino oscillations
(Universidade Federal de Minas GeraisUFMG, 2017-08-11)
In this work, we studied entanglement and decoherence in neutrino oscillations from a quantum metrology perspective. A summary of the quantum eld theoretic description of neutrinos was done and the main quantum mechanical ...
Superposição de estados comprimidos de dois modos e aplicações em informação quântica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-03-07)
In this work, we present a new class of quantum states for applications in quantum
metrology and quantum information, the states here named as “Even EPR” and “Odd
EPR”. We present a review of the basic concepts of ...

A quantum uncertainty relation based on Fisher's information
(IOP Publishing, 2011-02)
We explore quantum uncertainty relations involving the Fisher information functionals Ix and Ip evaluated, respectively, on a wavefunction Ψ(x) defined on a D-dimensional configuration space and the concomitant wavefunction ...
