Quantum-Enhanced Graph Neural Network Boosts HIV and Alzheimer's Drug Screening Accuracy
核心洞察
Chinese researchers used a quantum-enhanced graph neural network on the Origin Wukong superconducting quantum computer to improve HIV (搜索) antiviral drug screening accuracy from 73% to 97%.
The same quantum approach raised Alzheimer's drug prediction accuracy from 64% to 70%, signaling early real-world value for quantum computing in drug discovery.
The work, led by Origin Quantum (搜索) and University of Science and Technology of China (搜索), reflects a broader shift of quantum technology from laboratory research toward healthcare applications.
Chinese scientists have reported a breakthrough in drug discovery powered by quantum technology, demonstrating that quantum computing can meaningfully improve the accuracy of pharmaceutical screening. Researchers from Chinese tech company Origin Quantum (搜索) and the University of Science and Technology of China (搜索) (USTC) developed a quantum-enhanced graph neural network running on China's independently developed superconducting quantum computer, Origin Wukong, that boosted HIV (搜索) antiviral drug screening accuracy from 73 percent to 97 percent and Alzheimer's drug prediction accuracy from 64 percent to 70 percent.
The advance highlights how a field once regarded as a distant scientific ambition is steadily transitioning from the laboratory to real-world use, with applications already emerging in healthcare, scientific research, secure communications, and industrial computing.
Quantum Machine Learning in Drug Discovery
The quantum-enhanced graph neural network represents one of the most direct demonstrations to date of quantum computing's potential in pharmaceutical research. By applying quantum techniques to a graph neural network architecture, the Origin Quantum (搜索) and USTC team achieved a 24-percentage-point improvement in HIV (搜索) antiviral drug screening accuracy, lifting it from 73 percent to 97 percent. For Alzheimer's disease (搜索), drug prediction accuracy improved from 64 percent to 70 percent.
These gains were realized on Origin Wukong, a superconducting quantum computer developed independently in China. The results suggest that quantum computing can complement, rather than replace, classical approaches to computationally intensive problems in drug discovery.
A Broader Shift Toward Real-World Applications
While fully fault-tolerant quantum computers remain years away, the advances reflect a broader reality: different branches of quantum technology are beginning to mature at different speeds. Quantum communication has moved furthest toward commercialization, with more than 40 major Chinese cities having deployed metropolitan quantum communications networks.
Quantum technology is also beginning to reshape healthcare more broadly. Every heartbeat generates an extremely weak magnetic field that conventional medical instruments cannot directly detect, but quantum sensors can measure these tiny signals. One example is a magnetocardiography system developed by Chinese quantum technology company CIQTEK (搜索), which uses quantum spin magnetometers to complete a cardiac scan in just a few minutes, providing physicians with a new tool for early cardiovascular screening and risk assessment. The technology has already been deployed at several major hospitals in China.
Complementing Classical Computing
For now, the most promising path toward practical quantum computing lies not in replacing today's supercomputers, but in combining the strengths of both technologies. Inside the next-generation computing cluster in Hefei, capital of Anhui province, China's first locally deployed hybrid quantum supercomputing center combines a high-performance supercomputer with two superconducting quantum computers and one trapped-ion quantum computer.
"We break a large computational problem into smaller tasks," said Wang Guyue, director of the project management center at Hefei Big Data Asset Operation Co, operator of the computing center. "Subproblems that have relatively simple inputs and outputs but extremely complex calculations are processed by quantum computers, while the remaining tasks stay on the classical system. We see quantum computing as complementing rather than replacing classical computing."
Commercial Momentum and International Expansion
The commercial potential of quantum technology is already beginning to emerge. Over the past two decades, Hefei has developed one of China's largest quantum technology ecosystems, bringing together more than 100 companies across the industrial chain. To accelerate commercialization, Anhui has launched an initiative encouraging quantum technologies to be tested in hundreds of real-world scenarios, and Hefei is establishing a 10-billion-yuan ($1.48 billion) fund to support emerging technologies, including quantum technology, according to Chen Jun, director of the Anhui provincial development and reform commission.
Chinese quantum companies are also expanding internationally. Origin Quantum (搜索) has begun exporting quantum computing equipment and cloud computing services, particularly to Belt and Road countries. In July 2026, Thailand's Chulalongkorn University announced a partnership with USTC and Chinese quantum computing company Unitary Quantum to jointly build Thailand's first trapped-ion quantum computer.
While many challenges remain before large-scale quantum computing becomes commonplace, the industry's focus has already shifted from proving that quantum technology works to discovering where it can create real economic and social value.
