A Chinese quantum computer, which launched worldwide this week, has been boosted to 176 qubits, media in that country is reporting. The Center for Excellence in Quantum Information and Quantum Physics under the Chinese Academy of Sciences, developed the Zuchongzhi quantum computing platform.

Zhu Xiaobo, the project’s chief engineer and a professor at the University of Science and Technology of China (USTC), explained that the research team enhanced the existing Zuchongzhi-2 chip, which originally had 66 qubits, by incorporating control interfaces for an additional 110 coupled qubits, according to a story on Xinhua’s English language site. This upgrade allows users to manipulate a total of 176 quantum bits.

Introduced in 2021, Zuchongzhi-2 is a programmable quantum computing system that can perform large-scale random quantum circuit sampling approximately 10 million times faster than the fastest supercomputer at the time of its creation, the news service reports.

Zhu added that Zuchongzhi aims to achieve advanced global standards in crucial design indicators such as connectivity, fidelity and interference time.

During a press conference, Peng Chengzhi, the executive vice-director of the project and chairman of QuantumCTek Co., Ltd., announced that the platform is accessible to users worldwide. The general public can engage in simple quantum computing programming and image experiments, while industry users can explore new applications through remote access to the quantum computers, Xinhua reports.

Peng expressed his enthusiasm for welcoming a growing number of users to experience the platform, asserting that quantum computing has the potential to propel the entire field forward. He also disclosed plans to establish connections between multiple high-performance quantum computers and the platform in the future, ensuring it remains up-to-date and backed by world-class technology.
