Buchou Quantum Unveils ‘Liangchou-1’: China’s First Atomic Quantum AI Foundation Platform at WAIC 2026

At the 2026 World AI Conference (WAIC) held in Shanghai from July 17 to 20, Shanghai Buchou Quantum Technology officially unveiled ‘Liangchou-1’ (Q-Cub), China’s first atomic quantum AI foundation platform. The product marks a transition of Chinese quantum computing from physical feasibility verification into engineering delivery and application validation, backed by endorsements from international academia and the financial sector.

Liangchou-1 builds on original theoretical breakthroughs by the team of Professor Li Xiaopeng from Fudan University’s Physics Department. Their stochastic enhanced quantum neural network research was published in Physical Review Letters, pushing observation expectation learning error to the 10⁻¹⁰ level. Their adaptive quantum reservoir computing method, published in Science Bulletin, demonstrated forex forecasting with only 0.3% relative error. JPMorgan Chase’s global technology research group cited the method as capable of “more accurately depicting the stochastic evolution of exchange rates than classical methods.”

On hardware, Liangchou-1 achieves over 1,500 qubits with 99.9% single-qubit fidelity, 99%+ Rydberg gate fidelity, and atomic loss rate strictly below 0.1%. The system supports full atomic rearrangement, ensuring reliability for complex computations.

The platform’s key innovation is its ‘three-compute fusion’ heterogeneous architecture, integrating neutral-atom QPU for quantum circuit execution, GPU clusters for quantum simulation and AI inference, and classical CPUs for business integration and compilation scheduling. A self-developed scheduler orchestrates all three compute types transparently, allowing algorithms to automatically benefit from quantum acceleration without awareness of the underlying hardware.

On the software side, Liangchou-1 ships with a six-layer full-stack architecture spanning hardware, execution engine, compilation optimization, programming interface, algorithm library, and applications. The Q-Cub SDK is open to global developers — a single ‘pip install q-cub’ command enables users to run their first quantum reservoir computing example within five minutes.

The platform has already built eight application ecosystems. In quantum weather intelligence, just 9 quantum spin nodes using reservoir computing can outperform 10,000 classical nodes. In embodied AI, Buchou Quantum partnered with Yanluo Robotics to apply quantum approximate optimization to 7-DOF robotic arm inverse kinematics, achieving sub-millimeter end-effector error, under 50ms solving time, and 99% success rate.

Buchou Quantum also co-established the ‘Neutral Atom Quantum Intelligence Lab’ with the Shanghai Qi Research Institute and Fudan University, focusing on intelligent quantum error correction, quantum reservoir computing, and fault-tolerant quantum intelligence. Liangchou-1 comes in three configurations: Cloud-Linked for academic research, Appliance for enterprise R&D, and Infrastructure for large-scale institutional deployments.
