Flatness-based control of a single qubit gate
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
This work considers the open-loop control problem of steering a two-level quantum system from any initial to any final condition. The model of this system evolves on the state space X = SU(2), having two inputs that ...
Probing the degree of non-Markovianity for independent and common environments
(2013-07-08)
We study the non-Markovianity of the dynamics of open quantum systems, focusing on the cases of independent and common environmental interactions. We investigate the degree of non-Markovianity quantified by two distinct ...

Criptografia de qubits de férmions de Majorana por meio de estados ligados no contínuo
(Universidade Estadual Paulista (Unesp), 2017-12-01)
Nós investigamos teoricamente uma cadeia topológica de Kitaev conectada a dois pontos quânticos (QDs) hibridizados a terminais metálicos. Neste sistema, observamos o surgimento de dois fenômenos marcantes: (i) uma ...

Encrypting Majorana fermion qubits as bound states in the continuum
(2017-07-13)
We theoretically investigate a topological Kitaev chain connected to a double quantum-dot (QD) setup hybridized with metallic leads. In this system we observe the emergence of two striking phenomena: (i) a decrypted Majorana ...
"Probabilidades negativas" e tomografia de Qubits
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2007-03-28)
In this dissertation we approached the tomography of discrete systems, understood as the representation
and the reconstruction of states. For the tomography we used distribution functions
of symmetrical pseudo-probabilities. ...
Quantum teleportation of an arbitrary two-qubit state and its relation to multipartite entanglement
