Sampling-based quasiprobability simulation for fault-tolerant quantum error correction on the surface codes under coherent noise

Shigeo Hakkaku, Kosuke Mitarai, Keisuke Fujii

We propose a sampling-based simulation for fault-tolerant quantum error correction under coherent noise. A mixture of incoherent and coherent noise, possibly due to over-rotation,…
