论文摘要
除量子纠缠外，量子不和谐已被证明是量子优势的资源。尽管许多实验表现出了经典的纠缠类比，但对于不和谐而言，没有做到这一点。我们提出了一种概念验证演示，用于使用经典的光使用经典的光，以利用两个量子的状态与拉格雷 - 高斯光束的空间模式之间的类比。我们通过将理论模拟的强度谱与不同不和谐值的实验结果进行比较，证明了这种方法的有效性。这种量子不和谐的经典类似物可能会进一步了解利用不和谐的量子信息技术的理解和开发。
Quantum discord has been shown to be a resource for quantum advantage in addition to quantum entanglement. While many experiments have demonstrated classical analogies of entanglement, none have done so for discord. We present a proof-of-concept demonstration for creating a classical analogue of quantum discord using classical light that takes advantage of the analogy between the state of two qubits and the spatial modes of a Laguerre-Gauss beam. We demonstrate the validity of this approach by comparing the intensity profiles of theoretical simulations to experimental results for different values of discord. Such a classical analogue of quantum discord may provide further insight in understanding and development of quantum information technologies that make use of discord.
