Single-shot quantum error correction
ONSITE ONLY!
Fault-tolerant protocols and quantum error correction (QEC) are essential to building reliable quantum computers from imperfect erroneous components. Optimizing the resource and time overheads needed to implement QEC is one of the most pressing challenges. In this talk, I will introduce a new topological QEC code, the three-dimensional subsystem toric code (3D STC). I will explain how the 3D STC allows for single-shot QEC, i.e., reliable QEC with no time overhead even in the presence of measurement errors. Due to its high QEC threshold together with local parity checks of small weight, the 3D STC is particularly appealing for realizing fault-tolerant quantum computing.Based on A. Kubica, M. Vasmer, Nat. Commun. 13, 6272 (2022).
