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…
Homology, Hopf Algebras and Quantum Code Surgery
Alexander Cowtan
This thesis is a study of quantum error-correction codes from an algebraic perspective. We concern ourselves not only with quantum codes but also protocols to perform logical quant…
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…
Parallel Logical Measurements via Quantum Code Surgery
Alexander Cowtan, Zhiyang He, Dominic J. Williamson +1
Quantum code surgery is a flexible and low overhead technique for performing logical measurements on quantum error-correcting codes, which generalises lattice surgery. In this work…
