In fact, even the world's fastest supercomputer would take longer than the life age of the universe to find the two numbers that multiply to give this one.

事实上，即使是世界上最快的超级计算机也需要比宇宙生命年龄更长的时间来找到相乘的两个数才能得出这个数。

While today's fastest supercomputer couldn't find those factors in the life age of the universe, a quantum computer could easily factorize numbers way, way bigger than that one.

虽然当今最快的超级计算机无法在宇宙的生命周期中找到这些因素，但量子计算机可以轻松地将数字因式分解， 比那个大得多。
