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 ...
Mecânica quântica no espaço de fase não-comutativo e aplicações em termodinâmica
(Universidade Federal de São Carlos, 2016-08-26)
In this work we study theoretical aspects arising from the fact of considering a
quantum theory with general relations of noncommutativity. Through the quantum
mechanics in phase-space formalism in the Wigner-Weyl ...
