Increasingly sophisticated quantum computers motivate the exploration of their abilities in certifying genuine quantum phenomena. Here, we demonstrate the power of state-of-the-art IBM quantum computers in correlation experiments inspired by quantum networks. Our experiments feature up to 12 qubits and require the implementation of paradigmatic Bell-State Measurements for scalable entanglement-swapping. First, we demonstrate quantum correlations that defy classical models in up to nine-qubit systems while only assuming that the quantum computer operates on qubits. Harvesting these quantum advantages, we are able to certify 82 basis elements as entangled in a 512-outcome measurement. Then, we relax the qubit assumption and consider quantum nonlocality in a scenario with multiple independent entangled states arranged in a star configuration. We report quantum violations of source-independent Bell inequalities for up to ten qubits. Our results demonstrate the ability of quantum computers to outperform classical limitations and certify scalable entangled measurements.

越来越复杂的量子计算机促使人们探索它们在证明真正的量子现象方面的能力。在这里，我们在受量子网络启发的相关实验中展示了最先进的 IBM 量子计算机的强大功能。我们的实验具有多达 12 个量子位，并且需要实施典型的贝尔状态测量以实现可扩展的纠缠交换。首先，我们展示了在多达九个量子位系统中与经典模型相悖的量子相关性，同时仅假设量子计算机在量子位上运行。凭借这些量子优势，我们能够证明纠缠在 512 结果测量中的 82 种基本元素。然后，我们放宽量子位假设，并在多个独立纠缠态以星形配置排列的情况下考虑量子非局域性。我们报告了多达 10 个量子比特的与源无关的贝尔不等式的量子违规。我们的结果证明了量子计算机能够超越经典限制并证明可扩展的纠缠测量。
