While the prior-shared entangled state is non-maximally, superdense coding can be completed only with some probability of success.

而如果事先共享的纠缠纯态处于非最大纠缠态，那么只能以一定的概率实现两比特经典信息的交流。

As for the residents of our superdense asteroid, they'd have to be careful; if they ran too fast, they'd be in serious danger of entering orbit, going into a tumble and losing their lunch.

但对于在这颗超级密实的星球上居住的人来说，他们可要小心一些：如果他们跑得太快，就很有可能飞进轨道，翻转成一团，并把午餐吐出来。

White dwarfs are the hot, superdense remnants of spent stars. In a binary system called J0651, two white dwarfs circle each other very rapidly.

白矮星是一种高热度、高密度的晚期恒星。在这个编号J0651的双星系统内，有两颗恒星相互围绕飞快转动。
