SymBreak: Mitigating Quantum Degeneracy Issues in QLDPC Code Decoders by Breaking Symmetry
Keyi Yin, Xiang Fang, Jixuan Ruan +7
Quantum error correction (QEC) is critical for scalable and reliable quantum computing, but existing solutions, such as surface codes, incur significant qubit overhead. Quantum low…
CaliScalpel: In-Situ and Fine-Grained Qubit Calibration Integrated with Surface Code Quantum Error Correction
Xiang Fang, Keyi Yin, Yuchen Zhu +8
Quantum Error Correction (QEC) is a cornerstone of fault-tolerant, large-scale quantum computing. However, qubit error drift significantly degrades QEC performance over time, neces…
PowerMove: Optimizing Compilation for Neutral Atom Quantum Computers with Zoned Architecture
Jixuan Ruan, Xiang Fang, Hezi Zhang +3
Neutral atom-based quantum computers (NAQCs) have recently emerged as promising candidates for scalable quantum computing, largely due to their advanced hardware capabilities, part…
Surf-Deformer: Mitigating Dynamic Defects on Surface Code via Adaptive Deformation
Keyi Yin, Xiang Fang, Yunong Shi +3
In this paper, we introduce Surf-Deformer, a code deformation framework that seamlessly integrates adaptive defect mitigation functionality into the current surface code workflow.…
