AI 中文摘要
在不假设任何特定基础物理理论的情况下认证非经典性，既构成了一项基础性挑战，也是设备无关协议的要求。在可扩展架构中实现这种理论无关的认证，对于将基础测试与新兴量子技术联系起来至关重要。集成光子电路是可扩展量子信息处理的领先平台，这推动了开发严格方法来认证支撑量子优势的非经典资源。在本文中，我们报告了在三模集成光子电路上对广义情境性的理论无关认证。我们的方法将理论无关层析成像与单纯形可嵌入性认证（一种不要求对基础物理理论作任何假设的框架）相结合，并将其应用于由单光子注入的三模光子电路的实验数据。一个独立构建的量子模型为观察到的非经典性提供了一致性检查，但并未作为理论假设进入认证过程。该方法排除了我们实验数据的单纯形可嵌入性，提供了稳健的、理论无关的证据，表明我们的光子电路展现出非经典性。
英文摘要
Certifying nonclassicality without assuming any particular underlying physical theory constitutes both a foundational challenge and a requirement for device-independent protocols. Realizing such theory-independent certification in scalable architectures is essential for connecting fundamental tests with emerging quantum technologies. Integrated photonic circuits are a leading platform for scalable quantum information processing, motivating the development of rigorous methods to certify the nonclassical resources underpinning quantum advantage. In this paper, we report a theory-independent certification of generalized contextuality on a three-mode integrated photonic circuit. Our approach combines theory-agnostic tomography with simplex-embeddability certification---a framework that requires no assumptions about the underlying physical theory---and applies it to experimental data from a three-mode photonic circuit seeded by single photons. An independently constructed quantum model of the experiment provides a consistency check on the observed nonclassicality, without entering the certification as a theoretical assumption. The method rules out simplex-embeddability for our experimental data, providing robust, theory-independent evidence that our photonic circuit exhibits nonclassicality.
