VQA Segmentation Overview

Architecture for segmenting an image by transforming it into a graph and solving the corresponding minimum cut as a QUBO problem using variational quantum circuits

Overview

Welcome to NISQ-Seg, the official repository for the paper "Qubit-efficient Variational Quantum Algorithms for Image Segmentation", accepted at the Quantum Computing and Engineering 2024 (QCE'24) conference by IEEE. This repository provides the full pipeline for reproducing the experimental results and demonstrations of the three primary encoding methods introduced in the paper:

VQA Segmentation Overview

Image is converted to an undirected weighted graph with similarity of the pixels as the edge weight metric, then solving the minimum cut obtains the segmentation of the image.
  1. Parametric Gate Encoding (PGE)
  2. Ancilla Basis Encoding (ABE)
  3. Adaptive Cost Encoding (ACE)

These quantum techniques are optimized for Noisy Intermediate-Scale Quantum (NISQ) devices and demonstrate efficient qubit usage for graph-based image segmentation tasks. You can explore the different encoding methods by running the provided Jupyter notebook (tutorial.ipynb).

Paper Preprint

The preprint is available on arXiv. The original implementation (in Qiskit) is also available on GitHub
