Distilling Magic States in the Bicycle Architecture
Shifan Xu, Kun Liu, Patrick Rall +2
Magic State Distillation is considered to be one of the promising methods for supplying the non-Clifford resources required to achieve universal fault tolerance. Conventional MSD p…
Max-Window Scale Estimation for Near-Lossless HiF8 W8A8 Quantization-Aware Training
Yingying Cheng, Jinquan Shi, Li Zhou +4
Quantization-aware training (QAT) with low-bit floating-point formats enables efficient LLM deployment, yet introduces subtle failure modes invisible to standard training metrics.…
In-Situ Simultaneous Magic State Injection on Arbitrary CSS qLDPC Codes
Kun Liu, Shifan Xu, Tomas Jochym-O'Connor +3
Quantum low-density parity-check (qLDPC) codes can encode many logical qubits within a single code block at low physical qubit overhead, yet magic state injection into such codes r…
Parsimonious Quantum Low-Density Parity-Check Code Surgery
Andrew C. Yuan, Alexander Cowtan, Zhiyang He +2
Quantum code surgery offers a flexible, low-overhead framework for executing logical measurements within quantum error-correcting codes. It encompasses several fault-tolerant logic…
