China's first interconnectable neutral atom quantum computer "Qianzhen" prototype was released in Hefei

China News Service, Hefei, November 8 (Reporter Zhang Jun) China's first interconnectable neutral atom quantum computer "Qianzhen" prototype was released in Hefei, Anhui Province on the 8th.

Neutral atom quantum computing is one of the current mainstream technical routes for quantum computing. This technical route uses "optical tweezers" arrays to trap neutral atoms to construct qubits. It has the characteristics of strong scalability, high computational fidelity, and easy multi-machine collaborative interconnection. It is an important direction for realizing universal quantum computing.

The prototype of "Qianzhen" was developed by Hefei Qianyuan Quantum Technology Co., Ltd. (hereinafter referred to as "Qianyuan Quantum"). According to Li Gang, professor at the Institute of Optoelectronics of Shanxi University and chairman of Qianyuan Quantum, the "Qianzhen" prototype incorporated interconnection technology from the beginning of its architecture design and is China's first neutral atom quantum computer prototype with multi-machine interconnection capabilities.

Li Gang said that Qianyuan’s quantum research team has full-link independent research and development capabilities from core devices, quantum processor systems to multi-machine interconnection technology. "In the future, the team plans to break through the upper limit of single-machine computing power through a multi-machine cluster model, carry out interconnection verification and demonstration for scientific research and industry users, and provide a feasible technical path for the expansion of larger-scale quantum computing power."

On the same day, the Shanxi University-Qianyuan Quantum Neutral Atom Quantum Computing Joint Laboratory was unveiled. According to reports, the Qianyuan Quantum Project is an achievement transformation project of the National Key Laboratory of Optical Quantum Technology and Devices of Shanxi University. The joint laboratory will focus on key scientific issues and engineering problems such as optical tweezers atomic arrays, multi-machine interconnect interfaces, and core optical devices.

Hefei is one of the earliest cities in China to systematically lay out quantum technology research and development and industrialization, and has cultivated and gathered more than 100 quantum industry chain companies.
