Non-CSS Quantum Code Embedding
Andrew C. Yuan, Nouédyn Baspin
We generalize the unified framework in [Phys. Rev. A 113, 022438 (2026)] to accommodate arbitrary stabilizer codes (referred as non-CSS for emphasis). The generalization has immedi…
4D and 5D Layer Codes through Color Routing
Andrew C. Yuan, Nouédyn Baspin
We introduce and explicit Calderbank-Shor-Steane (CSS) code construction that generalizes the Layer codes to dimensions. Much like its predecessor, the present construction…
The Pinnacle Architecture: Reducing the cost of breaking RSA-2048 to 100 000 physical qubits using quantum LDPC codes
Paul Webster, Lucas Berent, Omprakash Chandra +5
The realisation of utility-scale quantum computing inextricably depends on the design of practical, low-overhead fault-tolerant architectures. We introduce the Pinnacle Architectur…
Wire Codes
Nouédyn Baspin, Dominic Williamson
Quantum information is fragile and must be protected by a quantum error-correcting code for large-scale practical applications. Recently, highly efficient quantum codes have been d…
Quantum Weight Reduction with Layer Codes
Andrew C. Yuan, Nouédyn Baspin, Dominic J. Williamson
Quantum weight reduction procedures ease the implementation of quantum codes by sparsifying them, resulting in low-weight checks and low-degree qubits. However, to date, only few q…
Fast surgery for quantum LDPC codes
Nouédyn Baspin, Lucas Berent, Lawrence Z. Cohen
Quantum LDPC codes promise significant reductions in physical qubit overhead compared with topological codes. However, many existing constructions for performing logical operations…
