Why error correction matters为什么纠错很重要

This code is part of our broader strategy to bring useful quantum computing to the world.这个代码是我们为世界带来有用的量子计算的更广泛战略的一部分。

Today, our users benefit from novel error mitigation techniques — methods for reducing or eliminating the effect of noise when calculating observables, alongside our work suppressing errors at the hardware level. This work brought us into the era of quantum utility. IBM researchers and partners all over the world are exploring practical applications of quantum computing today with existing quantum systems. Error mitigation lets users begin looking for quantum advantage on real quantum hardware.如今，我们的用户受益于新型的误差缓解技术-在计算可观测量时减少或消除噪声影响的方法，以及我们在硬件层面抑制误差的工作。这项工作将我们带入了量子效用的时代。IBM全球的研究人员和合作伙伴正在利用现有的量子系统探索量子计算的实际应用。错误缓解让用户开始在真实的量子硬件上寻找量子优势。

But error mitigation comes with its own overhead, requiring running the same executions repeatedly so that classical computers can use statistical methods to extract an accurate result. This limits the scale of the programs you can run, and increasing that scale requires tools beyond error mitigation — like error correction.但是，错误缓解也有其自身的开销，需要重复运行相同的执行，以便经典计算机可以使用统计方法来提取准确的结果。这就限制了您可以运行的程序的规模，而要增加这种规模，就需要使用除错误缓解之外的工具--比如纠错。

Last year, we debuted a new roadmap laying out our plan to continuously improve quantum computers over the next decade. This new paper is an important example of how we plan to continuously increasing the complexity (number of gates) of the quantum circuits that can be run on our hardware. It will allow us to transition from running circuits with 15,000 gates to 100 million, or even 1 billion gates.去年，我们推出了一个新的路线图，列出了我们在未来十年内不断改进量子计算机的计划。这篇新论文是一个重要的例子，说明我们计划如何不断增加可以在我们的硬件上运行的量子电路的复杂性（门的数量）。它将允许我们从运行15，000个门的电路过渡到1亿个，甚至10亿个门。
