Automated logical Clifford gadgets for heterogeneous architectures via chain maps
Asmae Benhemou, Noah Berthusen
Transversal CNOTs are ubiquitous for entangling logical qubits of identical CSS codes pairwise. For distinct codes, the options are much more limited, and are typically known only…
Simple logical quantum computation with concatenated symplectic double codes
Noah Berthusen, Elijah Durso-Sabina
There have been significant recent advances in constructing theoretical and practical quantum error correcting codes that function well as quantum memories; however, performing fau…
Automorphism gadgets in homological product codes
Noah Berthusen, Michael J. Gullans, Yifan Hong +2
The homological product is a general-purpose recipe that forges new quantum codes from arbitrary classical or quantum input codes, often providing enhanced error-correcting propert…
Adaptive Syndrome Extraction
Noah Berthusen, Shi Jie Samuel Tan, Eric Huang +1
Device error rates on current quantum computers have improved enough to where demonstrations of error correction below break-even are now possible. Still, the circuits required for…
Toward a 2D Local Implementation of Quantum LDPC Codes
Noah Berthusen, Dhruv Devulapalli, Eddie Schoute +4
Geometric locality is an important theoretical and practical factor for quantum low-density parity-check (qLDPC) codes which affects code performance and ease of physical realizati…
Experiments with the 4D Surface Code on a QCCD Quantum Computer
Noah Berthusen, Joan Dreiling, Cameron Foltz +9
Single-shot quantum error correction has the potential to speed up quantum computations by removing the need for multiple rounds of syndrome extraction in order to be fault-toleran…
