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 ...
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 ...
Quantum state tomography and quantum logical operations in a three qubits NMR quadrupolar system
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2013-08-02)
In this work, we present an implementation of quantum logic gates and algorithms in a three effective qubits system, represented by a (I = 7/2) NMR quadrupolar nuclei. To implement these protocols we have used the strong ...

Optimal control of hybrid qubits: Implementing the quantum permutation algorithm
(2018-03-21)
The optimal quantum control theory is employed to determine electric pulses capable of producing quantum gates with a fidelity higher than 0.9997, when noise is not taken into account. Particularly, these quantum gates ...
Fast optical control of a coded qubit in a triple quantum dot
(IOP Publishing, 2019-02)
In this work, we study strategies for the optical control, within the dipole approximation, of a qubit encoded in the total intrinsic angular momentum states of three electrons confined in a triple quantum dot. The system ...
Unitarily inequivalent mutually unbiased bases for n qubits
(2014)
The standard construction of complete sets of mutually unbiased bases (MUBs) in prime power dimensions is based on the quadratic Gauss sums. We introduce complete MUB sets for three, four, and five qubits that are unitarily ...
