High performance quantum key distribution prototype system using a commercial off-the-shelf solution: experimental and emulation demonstrations
(2017)
A continuous variable-quantum key distribution system prototype that uses weak coherent states
with a diffused phase, commercial off-the-shelf devices, complete free space 90-degrees hybrid
and simplified quantum protocol ...

Quantum Correlations And Coherence In Spin-1 Heisenberg Chains
(American Physical Society, 2016)
Coherent control of localization, entanglement, and state superpositions in a double quantum dot with two electrons
(American Physical Society, 2009-01)
We have recently proposed a quantum control method based on the knowledge of the energy spectrum as a function of an external control parameter. So far, our method has been applied to connect the ground state to target ...
Quantum correlations and coherence in spin-1 Heisenberg chains
(2016-05-24)
We explore quantum and classical correlations along with coherence in the ground states of spin-1 Heisenberg chains, namely the one-dimensional XXZ model and the one-dimensional bilinear biquadratic model, with the techniques ...
Quantum thermodynamics of quantum critical systems
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2022-02-11)
Esta tese dedica-se ao estudo de sistemas que apresentam transições de fase quânticas contínuas sujeitos a um protocolo termodinâmico de trabalho. Particularmente, investigamos como as coerências quânticas criadas por uma ...
Quantum coherence and uncertainty in the anisotropic XY chain

Quantum thermodynamics aspects with a thermal reservoir based on PT -symmetric Hamiltonians
(2021-08-01)
We present results concerning aspects of quantum thermodynamics under the background of non-Hermitian quantum mechanics for the dynamics of a quantum harmonic oscillator. Since a better control over the parameters in quantum ...
