Abstract

This scientific initiation project (ScIn) aims the development of filters to adjust the format of pulses used to control quantum bits (qubits) used in the main project. It has the objective of design and manufacture filters that transform fast pulses (Delta function type) into pulses with Gaussian shape. In addition, the project develops new capacities in students in electronic circuitry and transmission lines techniques, as well, the study of qubits and superconducting circuits.
