对于大多数量子通信协议来说，纠缠的增强是必要的，其中许多协议定义在大于2的希尔伯特空间中。在这篇工作中，我们给出了轨道角动量纠缠光子纠缠集中的实验实现。我们研究了三维的具体情况和从初始状态产生不同纠缠态的可能性。这里给出的结果对于纯态和混合态都很重要。
Enhancement of entanglement is necessary for most quantum communication protocols many of which are defined in Hilbert spaces larger than 2. In this work we present the experimental realization of entanglement concentration of orbital angular momentum entangled photons. We investigate the specific case of three dimensions and the possibility of generating different entangled states out of an initial state. The results presented here are of importance for pure states as well as for mixed states.
