Recent claims of quantum advantage invite rigorous methodologies for evaluating the nonclassical resources exploited by quantum computers. While entanglement is undeniably a hallmark of quantum mechanics, results such as the Gottesman–Knill Theorem suggest that it may not fully account for the computational power of quantum computers, leaving open the possibility that entanglement is only part of the quantumness game.

In this talk, we propose a benchmarking strategy for near-term quantum devices based on Svetlichny inequalities, which are capable of detecting genuine multipartite nonlocality, a stronger quantum resource than bipartite entanglement. Starting from the metatheoretical assumption that foundational notions like locality and separability have operational relevance, we reinterpret these inequalities as resource witnesses and experimentally test them on actual quantum hardware, including IQM superconducting and AQT ion-trap devices.

By comparing theoretical and experimental violations of Svetlichny inequalities on large samples of randomly generated states, we assess the capacity of quantum platforms to preserve nonlocal correlations. This method offers a scalable, device-independent, and algorithm-free benchmarking framework rooted in the logical and physical structure of quantum theory.
