No-Cost Nonlocality Certification from Quantum Tomography

This paper presents a novel approach to certify quantum nonlocality using standard tomographic measurements (X, Y, Z) without requiring additional experimental resources. This is significant because it allows for the reinterpretation of existing tomographic data for nonlocality tests, potentially streamlining experiments and analysis. The application to quantum magic witnessing further enhances the paper's impact by connecting fundamental studies with practical applications in quantum computing.
