Model-Independent Quantum Phases Classifier
Felipe Mahlow, Fabrício S. Luiz, André L. Malvezzi +1
Machine learning has revolutionized many fields of science and technology. Through the -Nearest Neighbors algorithm, we develop a model-independent classifier, where the algorit…
Machine classification for probe based quantum thermometry
Fabrício S. Luiz, A. de Oliveira Junior, Felipe F. Fanchini +1
We consider probe-based quantum thermometry and show that machine classification can provide model-independent estimation with quantifiable error assessment. Our approach is based…
Quantum thermodynamics aspects with a thermal reservoir based on -symmetric Hamiltonians
Jonas F. G. Santos, Fabricio S. Luiz
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 b…
Non-Hermitian noncommutative quantum mechanics
Jonas F. G. Santos, Fabricio. S. Luiz, Oscar. S. Duarte +1
In this work we present a general formalism to treat non-Hermitian and noncommutative Hamiltonians. This is done employing the phase-space formalism of quantum mechanics, which all…
Heralded entangling quantum gate via cavity-assisted photon scattering
Halyne S. Borges, Daniel Z. Rossatto, Fabrício S. Luiz +1
We theoretically investigate the generation of heralded entanglement between two identical atoms via cavity-assisted photon scattering in two different configurations, namely eithe…
Gauge linked time-dependent non-Hermitian Hamiltonians
F. S. Luiz, M. A. de Ponte, M. H. Y. Moussa
In this work we address systems described by time-dependent non-Hermitian Hamiltonians under time-dependent Dyson maps. We shown that when starting from a given time-dependent non-…
Unitarity of the time-evolution and observability of non-Hermitian Hamiltonians for time-dependent Dyson maps
F. S. Luiz, M. A. Pontes, M. H. Y. Moussa
Here we present an strategy for the derivation of a time-dependent Dyson map which ensures simultaneously the unitarity of the time evolution and the observability of a quasi-Hermi…
Implementation of quantum logic gates using coupled Bose-Einstein condensates
F. S. Luiz, E. I. Duzzioni, L. Sanz
In this work, we are interested on the implementation of single-qubit gates on coupled Bose-Einstein condensates (BECs). The system, a feasible candidate for a qubit, consists on c…
Optimal continuous variable quantum teleportation protocol for realistic settings
F. S. Luiz, Gustavo Rigolin
We show the optimal setup that allows Alice to teleport coherent states to Bob giving the greatest fidelity (efficiency) when one takes into account two realistic assumptions. The…
Atom-mediated effective interactions between modes of a bimodal cavity
F. O. Prado, F. S. Luiz, J. M. Villas-Bôas +3
We show a procedure for engineering effective interactions between two modes in a bimodal cavity. Our system consists of one or more two-level atoms, excited by a classical field,…
