Quantum error correction with biased-noise qubits can drastically reduce the hardware
overhead for universal and fault-tolerant quantum computation. Cat qubits are a promising …

We present a comprehensive architectural analysis for a proposed fault-tolerant quantum
computer based on cat codes concatenated with outer quantum error-correcting codes. For …

Erasures, or errors with known locations, are a more favorable type of error for quantum
error-correcting codes than Pauli errors. Converting physical noise into erasures can …

Quantum error correction requires decoders that are both accurate and efficient. To this end,
union-find decoding has emerged as a promising candidate for error correction on the …

Magic states have been widely studied in recent years as resource states that help quantum
computers achieve fault-tolerant universal quantum computing. The fault-tolerant quantum …

Four-Fermi quantum field theories in (2+ 1) dimensions lie among the simplest models in
high-energy physics, the understanding of which requires a non-perturbative lattice …

The surface code is a prominent topological error-correcting code exhibiting high fault-
tolerance accuracy thresholds. Conventional schemes for error correction with the surface …

Magic state distillation is a resource intensive subroutine that consumes noisy input states to
produce high-fidelity resource states that are used to perform logical operations in practical …

Lookup-table decoding is fast and distance preserving, making it attractive for near-term
quantum computer architectures with small-distance quantum error-correcting codes. In this …

We give the Bacon-Shor code a threshold purely by deleting gates from its circuit.
Specifically: we use lattice surgery to concatenate the Bacon-Shor code with itself using …
