C12 Automates Pick & Place Nanoassembly to Standardize Carbon Nanotube Qubit Fabrication - Quantum Computing Report

Quantum hardware venture C12 has introduced Pick & Place, a patented nanoassembly process engineered to transfer single-walled carbon nanotubes (CNTs) onto pre-fabricated quantum circuits with micrometric precision. The fabrication method serves as a foundational manufacturing block to decouple high-temperature nanotube growth from sensitive, sub-micron chip lithography layers. By adapting advanced semiconductor packaging concepts to the nanoscale, the technique addresses a primary barrier in solid-state quantum engineering: structural and electronic qubit variability caused by direct-growth substrate defects. Technical Architecture & Electrical Qubit Prescreening The nanoassembly pipeline replaces conventional random-deposition methods, which expose underlying chip materials to degrading thermal thresholds and introduce structural [...]
