China Quantum Computer ‘Origin Wukong’: Superconducting Quantum Computer has 72 Qubits in Boost for Chinese Technology

China’s third-generation superconducting quantum computer, “Origin Wukong”, has been launched by Origin Quantum Computing Technology. The computer, powered by a 72-qubit “Wukong chip”, is the most advanced of its kind in China. The technology marks China’s first automated batch testing of quantum chips, increasing efficiency significantly, according to Kong Weicheng of the Anhui Quantum Computing Engineering Research Center.

The “Wukong chip” has 198 qubits in total (72 Working qubits and 126 coupler qubits), says Jia Zhilong of the Anhui Provincial Key Laboratory of Quantum Computing Chips. Origin Quantum, established in 2017, leads in quantum computing patents in China and ranks sixth globally.

China’s Third-Generation Superconducting Quantum Computer

China’s quantum computing has achieved a significant milestone with the launch of its third-generation superconducting quantum computer, “Origin Wukong”. Reported in the Global Times of China. It follows similar technology development to IBM and Rigetti in using superconducting qubits to power the device. Other technologies such as Ion Traps and Semiconductor qubits also exist in the market.

The computer was brought online at Origin Quantum Computing Technology (Hefei) Co. The computer is powered by a 72-qubit superconducting quantum chip known as the “Wukong chip”. This makes it the most advanced programmable and deliverable superconducting quantum computer in China, as per a joint statement from the Anhui Quantum Computing Engineering Research Center and the Anhui Provincial Key Laboratory of Quantum Computing Chips.

Superconducting Quantum Computer Technology

Superconducting quantum computers are quantum computers that operate based on superconducting circuit quantum chips. This technology is not unique to China, as both IBM and Google also use superconducting technology in their quantum computers. The “Origin Wukong” is equipped with Origin Quantum’s third-generation quantum computing measurement and control system. This marks China’s first instance of automated batch testing of quantum chips, which has led to a significant increase in the quantum computer’s efficiency.

The “Wukong Chip” and Its Capabilities

The “Wukong chip” that powers the “Origin Wukong” has a total of 198 qubits, which includes 72 working qubits and 126 coupler qubits. This information was shared by Jia Zhilong, a deputy director of the Anhui Provincial Key Laboratory of Quantum Computing Chips. The chip’s capabilities are a testament to the progress China has made in the field of quantum computing.

Origin Quantum has been a significant player in China’s quantum computing landscape. The company has already delivered its first- and second-generation superconducting quantum computers to the Chinese market. Established in 2017, the Hefei-based company was responsible for China’s first quantum chip production line, China’s first quantum computer operating system, and China’s first quantum computing measurement and control system. In terms of quantum computing patents, Origin Quantum is the leading company in China and ranks sixth globally.

In terms of specification, we can see from the website the following details for T1 (decoherence time): 15.22 μs and T2 (dephasing time): 2.23 μs. the ‘Wukong chip’ has a total of 198 qubits, including 72 working qubits and 126 coupler qubits.

Origin Quantum Computing Technology, founded in 2017 in Hefei High-Tech Zone, stands as a prominent figure in China’s quantum computing landscape. The company’s technological foundation is rooted in the CAS Key Laboratory of Quantum Information. Emphasizing the development of a comprehensive quantum computing industry ecosystem. Their efforts extend to the development of full-stack quantum computing solutions. A significant part of their mission involves actively advancing the industrialization of quantum computing technologies. This summary encapsulates the company’s core focus areas and its key role in the quantum computing sector in China.
