然后，时间来到了2019年10月。那个秋天的凌晨，在谷歌位于加州圣巴巴拉的研究园区里，一群工程师正围着一台名为“Sycamore”的量子芯片屏息以待。这台只有53个量子比特的芯片，在200秒内完成了一项特定任务。同样的任务，如果用当时世界上最强大的超级计算机"Summit"来完成同样的任务，需要一万年。2019年10月23日，谷歌正式在《Nature》杂志上发表论文，宣布实现了“量子优越性”——这是量子计算发展史上第一次，量子计算机在特定问题上超越了所有经典计算机。
Now that we've seen the problems with overlapping instances, let's look at the second coherence rule, which forbids orphan implementations. This restriction is most well-known for the following use case. On one hand, we have the serde crate, which defines the Serialize trait that is used pretty much everywhere. And then we have a library crate that defines a data type, say, a Person struct.
