论文摘要
我们研究了单个光子完美W-State的产生。这个完美的W-State的一个重要方面是，它可用于完美的传送和超密集编码，而最大的W-State无法实现。我们的生成方案涉及在紧凑且弱耦合的集成波导系统中单个光子自由度的各种路径自由度之间的纠缠，可以用飞秒激光直接写作技术精确地制造。这些平台在光子传播过程中具有稳定的稳定，可扩展性，可扩展性较低，对熔融的敏感性不太敏感，并确保非常低的损耗因子为0.1db/cm，因此非常适合生成完美的W型状态。除了产生单光子完美W-State，我们还使用现实的局部元素理论研究其非局部特性。
We study the generation of single photon perfect W-state. An important aspect of this perfect W-state is that, it can be used for perfect teleportation and superdense coding, which are not achievable with maximally entangled W-state. Our scheme for generation involves entanglement between various path degrees of freedom of a single photon in a compact and weakly coupled integrated waveguide system, which can be fabricated precisely with femtosecond laser direct writing technique. These platforms are interferometrically stable, scalable, less sensitive to decoherence and ensures a very low loss factor of 0.1dB/cm during photon propagation and hence are ideal for generation of perfect W-state. In addition to generation of single photon perfect W-state we study its non local properties using theory of local elements of reality.
