论文摘要
我们实验研究了以多种自由度显示同时纠缠的超室内状态的特性，并发现超出标准克劳瑟，霍恩，shimony，holt不平等的贝尔测试可以以独立的方式揭示较高维度的性质。具体而言，我们表明，超伦敦的国家不仅具有单独的自由度同时纠缠，而且还具有较高维度的希尔伯特空间中的纠缠。我们还通过转向不同的光子自由度来验证超座位量子状态的可引导性。
We experimentally investigate the properties of hyperentangled states displaying simultaneous entanglement in multiple degrees of freedom, and find that Bell tests beyond the standard Clauser, Horne, Shimony, Holt inequality can reveal a higher-dimensional nature in a device-independent way. Specifically, we show that hyperentangled states possess more than just simultaneous entanglement in separate degrees of freedom but also entanglement in a higher dimensional Hilbert space. We also verify the steerability of hyperentangled quantum states by steering different photonic degrees of freedom.
