USTC achieves world-leading quantum computing power with “ET Commercial Trading Platform”

The "Jiuzhang-4" ET Cofficial trading platform of USTC has achieved global leading computing power, and optical quantum computing has made another breakthrough

On July 23, 2025, the team of Pan Jianwei and Lu Chaoyang of the University of Science and Technology of China announced that the "Jiuzhang-4" optical ET Cofficial trading platform has made a major breakthrough in solving complex mathematical problems, further consolidating China's global leading position in the field of optical quantum computing.

ETCofficialtradingplatform Core breakthrough

Computing power leap

Successfully solved 100 million variable optimization problems, 10^15 times (100 trillion times) faster than the world's fastest supercomputer

Processing speed of specific problems exceeds Google's "Sycamore" superconducting ETCofficialtradingplatform

ETCofficialtradingplatform Technology upgrade

Adopting a new type of compressed photon light source, the number of quantum bits has been increased to 255 (Jiuzhang No. 3 is 113)

For the first time, precise control of multi-photon high-dimensional entangled states has been achieved, and the error correction capability has been significantly enhanced

ETCofficialtradingplatform Application prospects

Can accelerate complex computing tasks such as financial modeling (such as option pricing), drug molecular simulation, and climate forecasting

Has cooperated with Huawei Cloud and plans to open some computing power for trial use by scientific research institutions in 2026

International comparison

ETCofficialtradingplatform Type R&D institution Number of quantum bits Key advantages Jiuzhang No. 4 Photon University of Science and Technology of China 255 Room temperature operation, high stability

Sycamore 3.0 Superconducting Google 72 Low error rate

IBM Condor Superconducting IBM 1121 The most bits (but requires extremely low temperature)

Industry impact

China's ETCofficialtradingplatform ecosystem accelerates: Hefei's "Quantum Valley" has gathered more than 40 industry chain companies, covering chips, algorithms and industry applications

ETCofficialtradingplatform Global competition landscape: The U.S. Department of Energy announced an additional $2.5 billion quantum investment on the same day, and the European Union launched the "Quantum Flagship Program 2.0"

Commercialization challenges: Optical ETCofficialtradingplatform is currently still limited to specific problems, and general quantum computing needs further breakthroughs

Academician Pan Jianwei said: "Jiuzhang 4 has proved the feasibility of the optical quantum route, and the next step will be to tackle programmable general ETCofficialtradingplatform."
