Silicon Quantum Computing names W.H. Teh manufacturing chief

Silicon Quantum Computing has appointed W.H. Teh as Chief Manufacturing Officer, effective from October 2026.

Teh will oversee the expansion of the company's atomic semiconductor manufacturing as Silicon Quantum Computing advances its quantum systems programme. The Sydney-based group said he brings more than 20 years of operations leadership across semiconductor, photonics and AI infrastructure businesses.

His previous roles include leading US manufacturing at NVIDIA, spanning work from silicon through to systems assembly. Earlier, he held senior global operations roles at Excelitas Technologies, managed manufacturing operations at SanDisk and spent nearly a decade in semiconductor technology development and manufacturing at Intel.

The appointment adds another senior executive to the leadership team as the company builds out its manufacturing, finance and legal functions. Silicon Quantum Computing also appointed John Hollister as Chief Financial Officer and Karna Nisewaner as Chief Legal Officer this year.

Manufacturing focus

Teh's remit will centre on scaling Silicon Quantum Computing's atomic semiconductor manufacturing technology. The company designs, fabricates and operates its own quantum processors, describing itself as a vertically integrated manufacturer.

Its production approach is based on placing individual atoms in silicon with 0.13-nanometre accuracy. The company said this process supports current sales of AI and materials simulation chips, as well as its broader work on universal quantum computing systems.

According to the company, Teh has led multi-site manufacturing operations across North America, Europe and Asia. His background includes moving products from development into volume manufacturing, with experience in manufacturing footprint planning, supply chain integration and automation.

Michelle Simmons, Founder and Chief Executive Officer, said the appointment aligned with the company's next stage of growth.

"W.H. brings a unique skillset to the team: a combination of deep semiconductor expertise and a proven track record of building and scaling manufacturing for some of the world's leading technology companies. His background is directly in line with our growth trajectory, and we are delighted to have him on board," Simmons said.

Industry background

Teh joins the company with a technical and business background spanning chip manufacturing and operations management. He holds a PhD in semiconductor physics from the University of Cambridge's Cavendish Labouratory, a master's degree in electrical engineering and computer science from the Massachusetts Institute of Technology, and an MBA from the MIT Sloan School of Management.

That combination reflects the growing need across the quantum sector to pair scientific development with industrial execution, as companies face pressure not only to demonstrate research progress but also to turn specialist processes into repeatable manufacturing systems.

For Silicon Quantum Computing, that challenge is tied to its position as an integrated developer of quantum hardware. Running design, fabrication and operation in-house can offer tighter control over development, but it also increases the importance of manufacturing leadership as production moves beyond research settings.

Founded in 2017, the company is headquartered in Sydney. It says it has built on 25 years of underlying technological work and has been producing new chips on a weekly cycle through its in-house quantum processing unit manufacturing operations.

Teh described the role as focused on scaling both output and supply chain operations.

"SQC has developed an incredible capability in atomic-precision semiconductor manufacturing for end-to-end development of practical quantum systems. I'm here to scale manufacturing and supply chain to meet the demands of SQC's scientific roadmap, as well as our customers today and into the future," Teh said.
