China Takes a Quantum Leap with Origin Tianji 4.0, Its Fourth-Generation Quantum Control System

In a major step toward quantum technology self-reliance, China has officially launched Origin Tianji 4.0, the country’s fourth-generation self-developed quantum control system. Spearheaded by Origin Quantum Computing Technology Co., based in Hefei, Anhui Province, Tianji 4.0 is designed to support over 500 qubits, marking a new milestone in China’s journey to scalable, high-performance quantum computing.

The Tianji 4.0 system acts as the “neural center” of a quantum computer, responsible for sending highly precise electrical signals to quantum chips and interpreting their fragile quantum states. Compared to its predecessor, Tianji 3.0, the new version demonstrates significant improvements in scalability, integration, stability, and automation, laying a stronger foundation for engineering reproducibility and large-scale deployment.

What sets Tianji 4.0 apart is its full-stack integration with four major software platforms, enabling end-to-end workflows that were once confined to teams of PhDs. Now, standard engineering teams can execute sophisticated quantum control and measurement tasks, accelerating the commercial viability of quantum technologies in China.

The achievement is built on the legacy of Tianji 3.0, which powered the third-generation Origin Wukong quantum computer. Since its debut in January 2024, Wukong has completed over 380,000 quantum computing tasks for millions of users globally, spanning applications in finance, biomedicine, and scientific research. This real-world performance has validated the practical impact of China’s domestically engineered quantum systems.

The release of Tianji 4.0 is more than a hardware upgrade, it’s a signal of China’s growing independence in a field historically dominated by U.S. and European firms. With its scalable architecture and automation-friendly design, Tianji 4.0 paves the way for the mass production of hundred-qubit quantum computers, a capability few countries have approached at a system integration level.

This launch reinforces China’s pursuit of a self-controlled, homegrown ecosystem often referred to as the “China solution” in quantum computing. As the global race to quantum supremacy intensifies, Origin Tianji 4.0 positions China as a formidable contender, not only in scientific development but in engineering leadership and ecosystem readiness.

For a country aiming to reduce dependency on foreign quantum control systems, the successful deployment of Tianji 4.0 demonstrates that China is not just catching up, but may be preparing to leap ahead.
