摘要
曾有观点认为[T. Rudolph and B.C. Sanders, Phys. Rev. Lett. 87, 077903 (2001)]，光学频率下的连续变量量子隐形传态尚未实现，因为其使用的光源（激光器）并非“真正相干”。本文指出，“真正相干”始终是虚幻的，因为超越直接人类经验尺度上的绝对时间概念毫无意义。激光器与其他任何时钟一样好，即便在原理上亦如此，因此该对隐形传态实验的反对是毫无根据的。

6 pages, no figures, no equations, to be published in Journal of Modern Optics. This is a long version of quant-ph/0104004. I have not replaced that paper with this one because some authors have referenced that one approvingly who may feel differently about doing so to this version
