French Firm Developing Robotic Nano-Assembly Trick To Build 800-Qubit Quantum Chips

French quantum computing startup C12 is advancing a nano-assembly process for manufacturing individual carbon nanotube quantum processors, providing a new path toward scaling advanced hardware. The technique introduces mechanical precision to a manufacturing stage, that has traditionally lacked scalable uniformity.

The proprietary system utilizes a robotic arm, custom tools, and a patented nano-assembly technique to transplant approved nanotubes directly onto waiting chips. This method isolates and chemically protects individual electrons within the ultra-pure carbon nanotubes, creating a stable environment where errors can be controlled at the structural level.

According to the developers, the process enables scalable manufacturing of carbon nanotube quantum processors. The technology aims to provide a reliable path to scale quantum computers up to 800 qubits, bypassing the random deposition methods that often hinder standard hardware yields.

By automating the delicate pick-and-place operation, the startup intends to standardize the fabrication of spin-qubit architectures. This robotic assembly line offers a controlled end-to-end scientific workflow, that speeds up device readiness.
