On the Fault‐Tolerance Threshold for Surface Codes with General Noise
Abstract Fault‐tolerant quantum computing based on surface codes has emerged as a popular route to large‐scale quantum computers capable of accurate computation even in the presence of noise. Its popularity is, in part, because the fault‐tolerance or accuracy threshold for surface codes is believed to be less stringent than competing …
