Minimum-Weight Parity Factor Decoder for Quantum Error Correction
Yue Wu, Binghong Li, Kathleen Chang +2
Fast and accurate quantum error correction (QEC) decoding is crucial for scalable fault-tolerant quantum computation. Most-Likely-Error (MLE) decoding, while being near-optimal, is…
Network-Integrated Decoding System for Real-Time Quantum Error Correction with Lattice Surgery
Namitha Liyanage, Yue Wu, Emmet Houghton +1
Existing real-time decoders for surface codes are limited to isolated logical qubits and do not support logical operations involving multiple logical qubits. We present DECONET, a…
Micro Blossom: Accelerated Minimum-Weight Perfect Matching Decoding for Quantum Error Correction
Yue Wu, Namitha Liyanage, Lin Zhong
Minimum-Weight Perfect Matching (MWPM) decoding is important to quantum error correction decoding because of its accuracy. However, many believe that it is difficult, if possible a…
LEGO: QEC Decoding System Architecture for Dynamic Circuits
Yue Wu, Namitha Liyanage, Lin Zhong
Quantum error correction (QEC) is a critical component of FTQC; the QEC decoder is an important part of Classical Computing for Quantum or C4Q. Recent years have seen fast developm…
FPGA-based Distributed Union-Find Decoder for Surface Codes
Namitha Liyanage, Yue Wu, Siona Tagare +1
A fault-tolerant quantum computer must decode and correct errors faster than they appear to prevent exponential slowdown due to error correction. The Union-Find (UF) decoder is pro…
