Taiwan unveils 5-Qubit quantum computer for scientific research

Quantum computer with 5-qubit chips launched by Academia Sinica yesterday.

Academia Sinica, a Taiwanese research institution, has introduced a quantum computer based on 5-quantum-bit (qubit) chips, achieving a notable milestone in the nation’s quantum computing research and development. The computer, connected to the internet, is intended for use in scientific research by Academia Sinica’s members and partners. This accomplishment follows the creation of the 5-qubit chips in October of the previous year.

Chen Chii-dong, a research fellow at Academia Sinica’s Research Center of Applied Sciences, highlighted that the 5-qubit computer’s logic gate achieved an impressive 99.9 per cent fidelity rate. The development surpassed the Ministry of Science and Technology’s schedule, which initially aimed for the creation of 3-qubit chips by February of the prior year.

While substantial progress has been made in quantum computing technology, the practical application of this technology in commercial sectors or for personal use remains a considerable distance away. Academia Sinica emphasized that the 5-qubit computer is now available as a test and development platform for various research programs, including quantum computing, ultra-low-temperature complementary metal-oxide-semiconductor (CMOS), and operational amplifier research initiatives.

Despite receiving less time and resources compared to quantum computer research programs in other nations, Academia Sinica’s research team consistently outperformed expectations. President James Liao noted that these achievements are foundational, and resolving key issues is necessary before overcoming the next bottleneck in quantum computing technology.

Academia Sinica aims to lead the way in quantum computing for Taiwan’s private sector, creating momentum for sustained investment in talent and education. The quantum computing project involves collaboration between Academia Sinica, the Industrial Technology Research Institute, National Changhua Normal University, National Central University, National Chung Hsin University, the University of California, Santa Barbara, and the University of Wisconsin-Madison.
