Bell Correlation

Bell correlations, a stronger form of quantum correlation than entanglement, are being actively investigated to better understand and leverage quantum nonlocality. Current research focuses on developing efficient methods for detecting and quantifying these correlations in many-body systems, employing techniques like variational energy measurements and machine learning models, including neural networks tailored to preserve separability and handle incomplete data. These advancements are crucial for benchmarking quantum devices, improving quantum machine learning algorithms, and potentially enabling new applications in quantum information science.
