China Unveils Zuchongzhi 3.0 Quantum Computer, Surpassing Classical Supercomputers

China Deploys Zuchongzhi 3.0-Based Quantum Computer for Commercial Use

China has taken a bold step in the global quantum race with the commercial launch of its superconducting quantum computer built on the advanced Zuchongzhi 3.0 chip. Developed by China Telecom Quantum Group (CTQG) and QuantumCTek in Hefei, Anhui province, this new system features 105 readable qubits and 182 couplers, making it one of the most powerful quantum machines currently accessible worldwide. According to The Quantum Insider, the commercial system is available globally through the Tianyan quantum cloud platform, which has already processed more than 2 million experimental tasks for users in over 60 countries since its debut in November 2023.

Technical Breakthroughs: Zuchongzhi 3.0 Sets New Quantum Benchmark

The Zuchongzhi 3.0 chip signifies a major leap in quantum hardware innovation. Utilizing a dense two-dimensional lattice of superconducting qubits, the chip’s architecture enables flexible two-qubit interactions via 182 tunable couplers. This structure, coupled with a novel “flip-chip” integration technique and sapphire substrate, greatly improves signal integrity and thermal stability. As a result, the system achieves average qubit coherence times of up to 72 microseconds and gate operation fidelities above 99.9%—metrics that rival or closely match Google’s Willow processor, the leading U.S. competitor.

Quantum Speed: Outpacing Classical Supercomputers

The Zuchongzhi 3.0 quantum computer reportedly performs quantum random circuit sampling tasks quadrillion times faster than the world’s most advanced classical supercomputers. This performance also exceeds Google’s latest published results by a factor of one million, according to Chinese researchers. Chinese Academy of Sciences Such speed not only demonstrates quantum computational advantage—sometimes called “quantum supremacy”—but also positions China as a global leader in the practical deployment of quantum technologies.

Global Access and Academic Interest

Since November 2023, the Tianyan quantum cloud platform has processed over 2 million experimental tasks, attracting users from more than 60 countries. The platform has garnered more than 37 million visits, reflecting strong interest from academic, research, and industrial communities worldwide. The Quantum Insider While local and regional Chinese media have celebrated the achievement as a milestone of national pride and technological leadership, international coverage remains limited, with most details currently reported in Chinese and regional outlets.
