论文摘要
在此，我们使用将不连贯的混合状态的特性与不可能更快的光（FTL）信号传导相关的特性来检查两方纠缠。我们表明，如果似乎有一种方法可以区分由相同密度矩阵描述但使用不同的纯状态生成的粒子的集合，则可以使用纠缠的属性（即，非经典相关性）来创建FTL信号设备。我们不声称FTL信号是可能的，而是我们建立了当前物理理论的上述特性之间的逻辑联系，而这还尚未显而易见。
Hereby we inspect two-partite entanglement using thought experiment that relates properties of incoherently mixed states to the impossibility of faster-than-light (FTL) signalling. We show that if there appears a way to distinguish ensembles of particles that are described by the same density matrix, but are generated using different pure states - properties of entanglement (namely, non-classical correlations) could be employed to create an FTL signalling device. We do not claim FTL signalling is possible, rather, we establish the logical connection between the aforementioned properties of current physical theory which has not so far been evident.
