SpinQ and HKUST Joint Research on Quantum Error Correction Accepted by QEC 2026

April 23, 2026 – SpinQ Technology, a leading full-stack quantum computing solution provider, today announced that a collaborative research paper with the Hong Kong University of Science and Technology (HKUST) has been accepted for presentation at QEC 2026, the world’s premier conference focused on quantum error correction and fault-tolerant quantum computing.

The paper, Efficient high-threshold decoding for concatenated quantum Hamming codes with near-optimal effective distance, introduces a novel bidirectional hard-decision decoding algorithm that addresses critical bottlenecks in building practical, scalable fault-tolerant quantum systems.

Key Research Breakthroughs

-Innovative bidirectional decoding framework: Leverages higher-level syndrome information to refine lower-level recovery decisions, eliminating error accumulation common in traditional one-way local decoding.

-Dramatically improved fault-tolerance threshold:For the [[15,7,3]] concatenated quantum Hamming code, the fault-tolerance threshold increases from 1.56% to 4.35% under independent bit-flip noise.

-Near-optimal effective distance:Preserves near-theoretical code-distance scaling across multi-level concatenation, suppressing logical error rates exponentially faster than conventional decoders.

-Reduced hardware overhead:Lowers physical qubit consumption, enabling more efficient and practical fault-tolerant quantum computing architectures.

Quantum error correction is widely recognized as the foundational technology required to transition from today’s noisy intermediate-scale quantum (NISQ) devices to reliable, large-scale, fault-tolerant quantum computers. This work represents a major step toward translating advanced quantum coding theory into real-world engineering and commercial deployment.

Advancements in quantum error correction are critical for the future of practical quantum computing,”said a spokesperson for SpinQ.“This achievement validates our long-term investment in full-stack quantum R&D and our commitment to collaborating with top academic

institutions to accelerate innovation. We are proud to contribute meaningful progress to the global quantum ecosystem.”

QEC 2026 will take place in June 2026 in Santa Barbara, California, where the SpinQ-HKUST team will present the full details of their research.
