刘弘斌解释,目前所有量子计算机实现的是单双量子比特门操作,对应经典计算的加减乘除;而更复杂的运算如开方、取对数、阶乘,对应的是三量子比特门、四量子比特门操作。类似于Tofolli门这样的操作,是真实应用的量子电路中最常见的门操作。这样的多量子比特门在超导体系中受限于有限的量子比特连接性没有实现的可能和意义,但这些在中性原子体系中可以实现,而且可以为量子电路的执行,不管是运行速度还是保真度上带来巨大的收益。是公司未来重点突破的方向。并且,在量子纠错方面,公司计划利用“可擦除式误差”特性,探索更低开销的量子纠错方案,加速容错量子计算的实用化进程。

In other words, you get the precision of "map every character," without actually emitting a mapping per character. This is particularly powerful for transforms like "strip types," in which huge stretches of runtime code are identical.

Civil liberties groups, however, continue to accuse the company of doing the opposite—by helping the government surveil. The company’s relationship with U.S. Immigration and Customs Enforcement, in particular, which began under the Obama Administration, has invited intense scrutiny and criticism from both external critics and the company’s own employees—criticism that has only escalated over the last year as the Trump Administration has pushed ICE into an aggressive crackdown in cities like Minneapolis.
