Scalable Quantum Processors Using Standard Semiconductor Manufacturing Technology

digitalTestedTRL 5

Imagine trying to build a super-advanced computer using the same factories that make today's smartphone chips. Instead of inventing entirely new manufacturing plants, this project uses a special silicon layering technique to make quantum bits more reliable. It's like upgrading the blueprint of a chip so it can handle quantum calculations without losing its stability.
