摘要:
我们设计了Snowflake,一种量子错误校正解码器,针对表面码在电路级噪声下的表现,在准确性上比Union-Find解码器提高了约25%,且具有更优的平均运行时间缩放特性:亚二次而非三次方于码距。我们的解码器以流式方式运行,并具有分布式、本地的实现。在设计Snowflake时,我们提出了一种新的通用流解码方法,消除了现有窗口方法中由于窗口重叠导致的处理开销。
英文摘要:
We design Snowflake, a quantum error correction decoder that, for the surface code under circuit-level noise, is roughly 25% more accurate than the Union-Find decoder, with a better mean runtime scaling: subquadratic as opposed to cubic in the code distance. Our decoder runs in a streaming fashion and has a distributed, local implementation. In designing Snowflake, we propose a new method for general stream decoding that eliminates the processing overhead due to window overlap in existing windowing methods.
