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…
Error correction of a logical qubit encoded in a single atomic ion
Kyle DeBry, Nadine Meister, Agustin Valdes Martinez +6
Quantum error correction (QEC) is essential for quantum computers to perform useful algorithms, but large-scale fault-tolerant computation remains out of reach due to demanding req…
Efficient soft-output decoders for the surface code
Nadine Meister, Christopher A. Pattison, John Preskill
Decoders that provide an estimate of the probability of a logical failure conditioned on the error syndrome ("soft-output decoders") can reduce the overhead cost of fault-tolerant…
Correlated decoding of logical algorithms with transversal gates
Madelyn Cain, Chen Zhao, Hengyun Zhou +5
Quantum error correction is believed to be essential for scalable quantum computation, but its implementation is challenging due to its considerable space-time overhead. Motivated…
