    • Otimização dos campos de proteção nas técnicas de desacoplamento dinâmico contínuo 

      Zanni Junior, Paulo Eduardo (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 15/09/2023)
      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 ...

    • Teletransporte quântico na presença de ruído 

      Gomes, Raphael Fortes Infante (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 01/04/2016)
      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 

      Ruiz, Carlos Mario Rivera (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 03/10/2019)
      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 

      Mendonça, Taysa Mendes de (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 24/05/2021)
      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, ...

    • Platforms for quantum information and technology 

      Cardoso, Fernando Redivo (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 29/02/2024)
      This work presents a collection of scientific research results in the field of quantum information. The first paper describes the mathematical properties of a particular type of state of light, called the two-mode squeezed ...
