Study and application of QUnfold, an innovative Quantum Annealing-based Unfolding tool, using simulated ATLAS data

In recent years, quantum computing has emerged as a rapidly advancing field, though practical achievements remain limited due to significant technical challenges in constructing large-scale quantum computers. D-Wave currently stands as the only company offering a commercially accessible quantum annealer, enabling users to perform specific computations more efficiently. Taking advantage of this technology, we introduce QUnfold, a software designed to implement a novel unfolding technique, a key problem in particle physics, by harnessing the advantages of quantum computing. This work aims to evaluate the performance and limitations of this quantum-based approach compared to traditional methods. The evaluation is based on ATLAS simulated data from $t\bar t$ quark system events for entanglement measurement analysis.
