On January 29, 2026, Academia Sinica announced the successful development of a 20-qubit superconducting quantum computer, a new-generation system designed, fabricated, and integrated entirely in-house. The achievement followed the institute’s 2023 debut of Taiwan’s first domestically built 5-qubit machine, according to the Academia Sinica press release.
Academia Sinica President James C. Liao said the 20-qubit chip positions Taiwan among global frontrunners and marks the country’s entry into large-scale quantum chip fabrication. The team extended qubit coherence times from 15-30 microseconds in the 5-qubit system to 530 microseconds, allowing longer computation durations with fewer errors.
Chen Chii-dong, executive director of the Thematic Center for Quantum Computer, said the 20-qubit system expands computational variable space and demonstrates mastery of stable multi-qubit fabrication, coupling, and laser-based fine-tuning of qubit frequencies. The system was made available for domestic academic and research use, with plans to serve as an industrial testing platform for hardware-software integration and algorithm development.
