Termalização de qubits sujeitos à ação de reservatórios coletivos markovianos
(Universidade Federal de São Carlos, 2014-08-26)
We are interested in understanding the process of Markovian thermalization in quantum systems when we have one or two qubits interacting with a quantum electromagnetic field mode, using the Rabi model, in situations where ...
Quantum memory based on electromagnetically induced transparency in optical cavities
(Universidade Federal de São Carlos, 2015-04-16)
Engenharia de interações e de reservatórios
(Universidade Federal de São Carlos, 2008-05-17)
In this work we first present a protocol to build effective interactions between two cavity modes, considering a two-level atom under the action of classical fields. Bilinear Hamiltonians associated with parametric up- and ...
Engenharia de hamiltonianos e aplicações em teoria da informação quântica
(Universidade Federal de São Carlos, 2008-03-28)
Teletransporte quântico na presença de ruído
(Universidade Federal de São Carlos, 2016-04-01)
The main focus of this work is to explore the feasibility of conducting the
teleportation protocol in scenarios where the presence of an external environment
reduces the purity of the input state and the transmission ...
Optimal quantum control applied to quantum dots
(Universidade Federal de São Carlos, 2019-10-03)
In the present study, we review the one-qubit dynamics and we offer a new unifying interpretation of the Landau-Zenner and the Rabi dynamics, by indicating the physical elements responsible for the manifestation of one ...
Engenharia de reservatórios com temperaturas efetivas arbitrárias e máquinas térmicas quânticas para sistemas de spins nucleares
(Universidade Federal de São Carlos, 2021-05-24)
In this work we show how to engineer reservoirs with different effective temperatures for a single qubit (quantum bit) system. To that end, we built an appropriate interaction between a qubit, that is, a 13C nuclear spin, ...
Otimização dos campos de proteção nas técnicas de desacoplamento dinâmico contínuo
(Universidade Federal de São Carlos, 2023-09-15)
In this research project, we investigate the method known as \textit{continuous dynamical decoupling}, which is based on the use of continuously applied external fields to maximize the fidelity of quantum logical operations ...
