Fast magic state preparation by gauging higher-form transversal gates in parallel
Dominic J. Williamson
Magic states are a foundational resource for universal quantum computation. To survive in a realistic noisy environment, magic states must be prepared fault-tolerantly and protecte…
Dynamical quantum codes and logic gates on a lattice with sparse connectivity
Dominic J. Williamson, Bence Hetényi
We introduce several dynamical schemes that take advantage of mid-circuit measurement and nearest-neighbor gates on a lattice with maximum vertex degree three to implement topologi…
Fast and fault-tolerant logical measurements: Auxiliary hypergraphs and transversal surgery
Alexander Cowtan, Zhiyang He, Dominic J. Williamson +1
Quantum code surgery is a promising technique to perform fault-tolerant computation on quantum low-density parity-check codes. Recent developments have significantly reduced the sp…
Extractors: QLDPC Architectures for Efficient Pauli-Based Computation
Zhiyang He, Alexander Cowtan, Dominic J. Williamson +1
In pursuit of large-scale fault-tolerant quantum computation, quantum low-density parity-check (LDPC) codes have been established as promising candidates for low-overhead memory wh…
