Quantum Image Processing with Qiskit

This project demonstrates basic quantum image processing techniques using Qiskit, a quantum computing framework. It's based on the work from ica574's quantum-image-processing repository.

Overview

This code implements a quantum image processing algorithm that:

1. Downloads and processes a test image
2. Encodes the image into a quantum circuit
3. Applies a Quantum Fourier Transform (QFT)
4. Visualizes the results

Key Features

• Image to quantum state encoding
• Custom Quantum Fourier Transform implementation
• Bloch sphere visualization of quantum states
• Text-based quantum circuit visualization

How It Works

1. Image Processing:

   • Downloads a test image
   • Converts it to binary (black and white)
   • Flattens the image into a 1D array

2. Quantum Encoding:

   • Creates a quantum circuit where each qubit represents a pixel
   • Encodes the binary image data using basis encoding

3. Quantum Fourier Transform:

   • Applies a custom QFT to the encoded image circuit

4. Visualization:

   • Displays Bloch sphere representations before and after QFT
   • Prints a text representation of the final quantum circuit

Purpose

This project serves as a demonstration of how classical image data can be encoded into quantum states and manipulated using quantum operations. It's primarily intended for educational purposes and as a starting point for more complex quantum image processing algorithms.
