Local decoders for fault-tolerant quantum computation and translation-invariant stabilizer codes
Nathaniel Selub, Aditya Bhardwaj, Ethan Lake
We construct the first fully spatially local fault-tolerant quantum computer based on topological codes in fewer than four spatial dimensions. Our construction is a two-dimensional…

High-rate qLDPC processors
Aditya Bhardwaj, Muzhou Ma, Nadine Meister +6
Despite significant progress on quantum low-density parity-check (qLDPC) codes, building qLDPC processors that are high-rate, high-throughput, hardware-friendly, and fast-to-decode…
