Qubitclient Scope

Overview

Scope is a traditional numerical curve fitting module for quantum experiment analysis. It provides comprehensive parameter extraction tasks including peak detection, relaxation time fitting (T1/T2), oscillation analysis (Rabi, Ramsey), pulse optimization (DRAG), and 2D spectrum analysis. Unlike neural network-based approaches, Scope uses classical fitting algorithms for interpretable results.

Data Input Formats

The input data should be a dictionary or list of dictionaries with the following structure:

dict_list = [{
    "image": {
