SEEQC, a leader in digital quantum computing, has announced a new manufacturing partnership with Taiwan’s Industrial Technology Research Institute (ITRI). Together, the two organizations will establish a State-Of-The-Art production line dedicated to fabricating SEEQC’s proprietary Single Flux Quantum (SFQ) superconducting control chips, a key step in advancing the scalability and performance of SEEQC’s fully digital, chip-based quantum computing platform.
Through this collaboration, SEEQC will leverage the new facility to create a high-yield, reliable manufacturing environment. The project’s first phase will center on technology transfer and process development, guided by SEEQC’s research and development team, who will provide specialized technical expertise throughout. Once fabricated, the superconducting chips will be shipped to SEEQC’s U.S. headquarters for integration with qubits and testing at the company’s advanced cryogenic measurement facility.

These superconducting digital control chips operate at cryogenic temperatures alongside qubits, handling timing, readout, multiplexing and error-correction logic with ultra-low power, high speed and low latency, essential capabilities to building scalable, fault-tolerant quantum computers.
“Building this capability with a trusted partner creates a diversified manufacturing base for U.S. and global customers, beyond the existing chip fab in our New York headquarters, who need secure access to advanced superconducting electronics,” says Shu-Jen Han, Chief Technical Officer at SEEQC. “By combining ITRI’s outstanding engineering capabilities with our proprietary SFQ-based chip design and testing expertise, we are positioned to deliver scalable, reliable solutions to our global customers, accelerating the future of advanced superconducting electronics and digital quantum computing.”
“ITRI is committed to supporting the advancement of SEEQC’s superconducting chip manufacturing technologies,” says Shih-Chieh Chang, Vice President & General Director at ITRI. “Partnering with SEEQC enables us to apply our deep experience in advanced semiconductor processes developed in the past 30 years to a digital quantum architecture designed for large-scale manufacturing and deployment.”
Combined with SEEQC’s in-house R&D and chip manufacturing facilities in the United States, this partnership allows the company to expand manufacturing capacity efficiently, lowering operational costs and ensuring the reliable supply of critical components to customers, who include some of the largest technology companies worldwide. The expanded control-chip capacity will support SEEQC’s ongoing programs with partners including NVIDIA, the UK’s National Quantum Computing Centre (NQCC), and IBM, where its digital SFQ-based control architecture is being used to explore scalable quantum error correction and hybrid quantum–classical supercomputing in the recently announced Phase B of the DARPA sponsored Quantum Benchmarking Initiative (QBI).
The announcement underscores SEEQC and ITRI’s shared commitment to advancing global innovation in advanced chip manufacturing and building a resilient, distributed supply chain for emerging quantum and superconducting technologies.
