LightStim: A Framework for QEC Protocol Evaluation and Prototyping with Automated DEM Construction
Xiang Fang, Ming Wang, Yue Wu +6
Fault-tolerant quantum computing increasingly demands rigorous, circuit-level evaluation of diverse quantum error correction (QEC) protocols and efficient prototyping of new ones.…
Bridging Superconducting and Neutral-Atom Platforms for Efficient Fault-Tolerant Quantum Architectures
Xiang Fang, Jixuan Ruan, Sharanya Prabhu +4
The transition to the fault-tolerant era exposes the limitations of homogeneous quantum systems, where no single qubit modality simultaneously offers optimal operation speed, conne…
The Hitchhiker's Guide to Programming and Optimizing Cache Coherent Heterogeneous Systems: CXL, NVLink-C2C, and AMD Infinity Fabric
Zixuan Wang, Suyash Mahar, Luyi Li +9
We present a thorough analysis of the use of modern heterogeneous systems interconnected by various cachecoherent links, including CXL, NVLink-C2C, and Infinity Fabric. We studied…
OneAdapt: Adaptive Compilation for Resource-Constrained Photonic One-Way Quantum Computing
Hezi Zhang, Jixuan Ruan, Dean Tullsen +3
Measurement-based quantum computing (MBQC), a.k.a. one-way quantum computing (1WQC), is a universal quantum computing model, which is particularly well-suited for photonic platform…
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…
