Building a large-scale quantum computer requires effective strategies to correct errors that inevitably arise in physical quantum systems. Quantum error-correction codes present a way …
Accurate decoding of quantum error-correcting codes is a crucial ingredient in protecting quantum information from decoherence. It requires characterizing the error channels …

We present a method, called matching synthesis, for decoding quantum codes that produces an enhanced assignment of errors from an ensemble of decoders. We apply matching …
Recently, usage of detecting regions facilitated the discovery of new circuits for fault- tolerantly implementing the surface code. Building on these ideas, we present LUCI, a …
Real-time decoding is a key ingredient in future fault-tolerant quantum systems, yet many decoders are too slow to run in real time. Prior work has shown that parallel window …
