前不久,《少年科学》刊载青云的文章,介绍世界上科学家正在研究和试验一种绝对保密的量子密码。文章指出: 从数学上来讲,只要掌握恰当的方法,而且尝试的次数足够多,在现有各种密码中,没有哪种密码是解不开的。然而,有没有办法使得信息传输绝对可靠、难以破译呢?有!现在科学家正 Not long ago, “Juvenile Science” published Qing Yun’s article, introducing scientists in the world who are studying and experimenting with an absolutely confidential quantum code. The article points out: In terms of mathematics, as long as you have the right method and you have tried enough, there is no password that cannot be solved in all existing passwords. However, is there a way to make information transmission absolutely reliable and difficult to decipher? Yes! Now scientists are
