On December 20, the reporter learned from Hefei High-tech Zone that recently, the ion trap quantum computing platform ION I, developed and produced by Guoyi Quantum Technology (Hefei) Co., Ltd., was rolled off the assembly line in Hefei and officially delivered to users. The delivery equipment is developed by Guoyi Quantum and a domestic university user in the design, manufacturing, testing and other aspects of the system around the needs of scientific research scenarios, and will be used for research in the fields of quantum computing, quantum simulation and quantum algorithms. According to public reports, the platform is the first trapped-ion quantum computing platform in China to achieve commercial delivery.
Quantum computing is a new computing model based on quantum mechanics, which theoretically has powerful parallel computing capabilities far beyond classical computing, and can provide solutions to large-scale computing problems required by artificial intelligence, cryptanalysis, weather forecasting, drug discovery, etc. At present, quantum computing is still in the leapfrog stage from the laboratory to industrial application, and the development of quantum computing with different technical routes goes hand in hand, and each has its own advantages and disadvantages. Trapped-ion quantum computing technology has become one of the advantages in the development of quantum computers due to its characteristics of good connection between qubits, long coherence time, high fidelity of gate manipulation, and identical qubits.
The ION I ion trap quantum computing platform launched by Guoyi Quantum has the advantages of ultra-high integration and miniaturization, and the whole machine is composed of vacuum and trap system, optical path and frequency stabilization system, measurement and control and electronics system, laser and microwave control system, with high qubit fidelity and operation accuracy. The ION I trapped-ion quantum computer can control the number of bits 2~12 arbitrarily selectable, the fidelity of a single bit gate exceeds 99.97%, the fidelity of a two-bit gate exceeds 99.7%, and the coherence time T2* is greater than 100 ms. The system can stabilize the number of trapped ions over 90+, and the number of one-dimensional ion trap crystals does not change for several hours. A number of core technical indicators have reached the international first-class level.

Wu Ya, project leader of Guoyi Quantum Ion Trap Quantum Computer, said: "Based on the user's scientific research needs, the ION I Ion Trap Quantum Computing Platform fully integrates vacuum, laser and optical, radio frequency and microwave technologies, as well as electronic systems, and carries out modular design and standardized manufacturing. Its first commercial delivery indicates that the mainland scientific research team has a high level of R&D and certain productization and engineering capabilities in the field of trapped-ion quantum computing. In the future, Guoyi Quantum will work with users to give full play to the advantages of the trapped-ion quantum computing platform, carry out quantum computing algorithms and application research, and contribute to the breakthrough of quantum computing technology.
