Método de dinâmicas efetivas aplicado na análise da interação qubit-qubit em dispositivos supercondutores: a interação qubit-qubit no contexto da computação quântica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2022-02-23)
In this dissertation, we approach some aspects of quantum computing. At first, we detail the Deutsch-Jozsa algorithm and show how to implement it in real IBM quantum computers, available free of charge via remote access ...
Extracting Information from Qubit-Environment Correlations
(Nature Publishing Group, 2014-12-17)
Most works on open quantum systems generally focus on the reduced physical system by tracing out the environment degrees of freedom. Here we show that the qubit distributions with the environment are essential for a thorough ...
Quantum transistor using superconducting qubits
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2022-09-23)
In recent times, quantum computation has become a flourishing field of research with increasing investment due to its promise to revolutionize computing, increasing the speed of information processing to levels far beyond ...
Efficient steady-state-entanglement generation in strongly driven coupled qubits
(American Physical Society, 2021-09)
We report on a mechanism to optimize the generation of steady-state entanglement in a system of coupled qubits driven by microwave fields. Due to the interplay between Landau-Zener-Stückelberg-Majorana pumping involving ...
Decoherence from qubit-qubit dipolar interaction in an all silicon quantum computer
(Sociedad Mexicana de Física A.C., 2009)
Generalized conditional entropy optimization for qudit-qubit states
(American Physical Society, 2014-10)
We derive a general approximate solution to the problem of minimizing the conditional entropy of a qudit-qubit system resulting from a local measurement on the qubit, which is valid for general entropic forms and becomes ...
