论文摘要
量子纠缠最突出的特征之一是其在局部单一转换下的不变性，这意味着纠缠程度在自由空间传播过程中保持恒定。虽然对于量子和经典的模式是正确的，但在这里，我们演示了一种新型的经典模式，这些模式会在自由空间传播时经历纠缠衰减。我们通过数值模拟显示了这一点，并通过实验证实了这一点。我们的结果表明了经典模式的新型特性，这为新应用铺平了道路。
One of the most prominent features of quantum entanglement is its invariability under local unitary transformations, which implies the degree of entanglement remains constant during free-space propagation. While this is true for quantum and classically--entangled modes, here we demonstrate a novel type of classically-entangled modes that experience an entanglement decay upon free-space propagation. We show this by numerical simulations and corroborate experimentally. Our results evinces novel properties of classically-entangled modes, which pave the way to novel applications.
