Non-Markovian Light-Matter Dynamics in the Time Fractional Jaynes-Cummings Model with Modulated Coupling
Enrique C. Gabrick, Thiago T. Tsutsui, Danilo Cius +3
We investigate the fractional time description of a generalized quantum light-matter system modeled by a time-dependent Jaynes-Cummings (JC) interaction, with different coupling ty…
Quantum Resonator as a Directional Quantum Emitter
Luiz O. R. Solak, Bruno L. Vermes, Antonio S. M. de Castro +2
Single-photon sources are essential for testing fundamental physics and for the development of quantum technologies. In this work a single-photon source is investigated, based on a…
Building Block For Universal Continuous Variables Computation In Superconducting Devices
Bruno A. Veloso, Ciro M. Diniz, Luiz O. R. Solak +3
Continuous variable (CV) quantum computation offers an alternative to qubit-based computing by exploiting the infinite-dimensional Hilbert space of bosonic modes. Despite recent pr…
Revisiting the Jaynes-Cummings model with time-dependent coupling
Thiago T. Tsutsui, Danilo Cius, Antonio Vidiella-Barranco +2
The Jaynes-Cummings (JC) model stands as a fully quantized, fundamental framework for exploring light-matter interactions, a timely reflection on a century of quantum theory. The t…
Reproducing the effects of quantum deformation in the undeformed Jaynes-Cummings model
Thiago T. Tsutsui, Antonio S. M. de Castro, Fabiano M. Andrade
In the Jaynes-Cummings (JC) model, the time dependence in the coupling parameter allows changes in the forms of the Rabi oscillations. In the inverse problem approach (IPA), the ti…
Spin Squeezing via One-Axis Twisting in a Quadrupolar NMR system under relaxation effects
Adriane Consuelo Leal Auccaise, Antonio Sérgio Magalhães de Castro
This study investigates spin squeezed states in nuclear magnetic resonance (NMR) quadrupolar systems with spins and at room temperature, taking into account the eff…
