Quantum Ansatz Exploration

Explore how the complexity of variational quantum circuits (ansatz) impacts the performance of quantum machine learning models on real-world datasets.

Overview

This project dives into the fascinating world of quantum machine learning (QML), using Google Cirq to experiment with simple and complex ansatz designs. Through this, we aim to understand the relationship between ansatz complexity and classification performance, while maintaining execution efficiency.

In this repository, you will:

  • Train a quantum classifier on datasets with different ansatz configurations.
  • Visualize and compare performance metrics like accuracy, precision, recall, and F1-score.
  • Learn how to design and tweak ansatz circuits to optimize quantum models.

Whether you're a beginner in QML or exploring advanced concepts, this project is designed to educate, inspire, and simplify learning quantum computing concepts.

Features

✨ Customizable Ansatz: Learn to design circuits that balance complexity and performance.
⚡ Quick Execution: Designed to provide fast results for easy experimentation.
📊 Performance Visualization: Compare simple vs complex ansatz using bar charts.
🛠️ Google Cirq Implementation: A clean, modular implementation for quantum enthusiasts.
🎓 Educational Insights: Teaching-focused explanations to help students and beginners.

Datasets

We train the quantum model on real-world datasets:

  1. Statlog Heart Dataset
  2. Ionosphere Dataset

Both datasets are preprocessed, split into training, validation, and testing sets to evaluate performance systematically.
