China’s quantum computer has entered commercial use, marking a major milestone in practical quantum computing applications. The machine is based on the “Zuchongzhi 3.0” design and demonstrates world-leading computational power.
The superconducting system includes 105 operational qubits and 182 couplers. China Telecom Quantum Group and QuantumCTek Co., Ltd., both based in Hefei, Anhui Province, developed it.
This quantum computer performs quantum random circuit sampling at speeds quadrillion times faster than top classical supercomputers. Experts say this achievement strengthens China’s position in global next-generation computing technologies.
In March 2025, scientists including Pan Jianwei, Zhu Xiaobo, and Peng Chengzhi built the 105-qubit superconducting prototype “Zuchongzhi 3.0.” The project broke the world record for quantum computational advantage in superconducting systems.
Quantum computational advantage, or “quantum supremacy,” occurs when a quantum computer outperforms advanced classical systems in specific tasks. Zhang Xinfang, senior researcher at CTQG, said the machine shows “the strongest quantum computational advantage” to date.
The quantum computer will connect to the “Tianyan” cloud platform, giving users worldwide access. Since launching in November 2023, the platform has received over 37 million visits from more than 60 countries. Experimental tasks on the platform have exceeded 2 million.
Experts note that commercial deployment will accelerate research, innovation, and practical development of quantum applications. The system can improve cryptography, artificial intelligence, materials science, and complex simulations.
China’s commercial quantum computer also signals the country’s growing leadership in advanced technology. Policymakers and industry leaders view it as a step toward broader industrial, scientific, and economic applications.
Researchers plan to expand qubit counts, improve error correction, and integrate the system into more practical computational tasks. They hope it will serve as a model for global quantum research and commercial deployment.
In addition, linking the quantum computer to cloud services promotes global collaboration and accelerates scientific discoveries. Companies, universities, and research institutes worldwide can test advanced quantum algorithms.
By combining cutting-edge superconducting technology with accessible cloud platforms, China’s quantum computer is poised to advance both scientific exploration and commercial innovation worldwide.
