Building quantum computers with advanced semiconductor fab | IBM Quantum Computing Blog

Building quantum computers at scale means treating quantum chips like the state-of-the-art hardware that they are. It means fabricating them to the highest standards of quality—similar to the standards we use to fabricate chips for production-scale classical computers.

Today, IBM has revealed that IBM Quantum Loon and IBM Quantum Nighthawk—plus all future chips on the IBM Quantum Development Roadmap—are being fabricated at the Albany NanoTech Complex using state-of-the-art 300mm semiconductor wafer technology. The Albany NanoTech Complex is one of the world’s most advanced semiconductor fabs and the details of our quantum chip fab processes have been held under wraps to this point. But now, the team is eager to show off the technology, share how they pulled the project off, and deliver their vision for the future.

This story is about more than processing quantum chips on larger wafers. It’s about using the best possible minds, machinery, and processes to realize quantum…
