Google宣布自己已实现量子霸权

According to a report in the Financial Times, a team of researchers from Google led by John Martinis have demonstrated quantum supremacy for the first time.《英国金融时报》的一篇报告称之为，John Martinis率领的一个Google研究团队首次证明了量子霸权。This is the point at which a quantum computer is shown to be capable of performing a task thats beyond the reach of even the most powerful conventional supercomputer.当时找到一台量子计算机能已完成最强劲的传统超级计算机都无法已完成的任务。The claim appeared in a paper that was posted on a NASA website, but the publication was then taken down. Google did not respond to a request for comment from MIT Technology Review.这一声明经常出现在NASA网站上公开发表的一篇论文中，但随后被移除了。

《麻省理工科技评论》催促Google回应做出评论，但并未获得对此。Google struck an agreement last year to use supercomputers available to NASA as benchmarks for its supremacy experiments.去年Google要求将NASA能用的超级计算机作为霸权实验的标杆。According to the Financial Times report, the paper said that Googles quantum processor was able to perform a calculation in three minutes and 20 seconds that would take todays most advanced supercomputer, known as Summit, around 10,000 years.据《英国金融时报》报导，该论文称之为Google的量子处理器能在3分20秒内已完成现在最先进设备的超级计算机Summit一万年才能已完成的计算出来。

In the paper, the researchers said that, to their knowledge, the experiment marks the first computation that can only be performed on a quantum processor.该论文中研究人员称之为，据他们熟知这一实验“标志着第一个不能在量子处理器上展开的计算出来”。Quantum machines are so powerful because they harness quantum bits, or qubits. Unlike classical bits, which represent either a 1 or a 0, qubits can be in a kind of combination of both at the same time.量子计算机如此强劲是因为他们利用了量子比特或量子位。

经典的二进制只代表1或0，而量子位不一样，可以同时是两者的一种人组。Thanks to other quantum phenomena, which are described in our explainer here, quantum computers can crunch large amounts of data in parallel that conventional machines have to work through sequentially.好在了其他我们在说明中叙述过的量子现象，量子计算机可以分段运算大量数据，而传统计算机不能按顺序展开运算。

Scientists have been working for years to demonstrate that the machines can definitively outperform conventional ones.科学家已研究多年，想证明量子计算机意味著高于传统计算机。
