C12 Automates Pick & Place Nanoassembly to Standardize Carbon Nanotube Qubit Fabrication 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 variations across the hardware array. Under the Pick & Place model, carbon nanotubes—each approximately 100,000 times thinner than a human hair—are synthesized independently, mechanically isolated, and structurally qualified prior to surface integration. C12 is currently the only developer utilizing real-time electrical prescreening at the individual qubit layer, allowing engineers to verify the purity and alignment of each carbon-12 isotope container before permanent physical attachment. This modular assembly flow has yielded a measurable step change in manufacturing throughput. By streamlining and partially automating the micromanipulation sequence, C12 successfully completed the nanoassembly of 50 individual quantum devices over a four-week period, matching the company’s cumulative production volume for the entire year of 2025. This specialized precision was demonstrated on the company’s High-Density (HD) prototype chip architecture. First announced by Co-Founder Pierre Desjardins at the Q2B conference in San Francisco, the HD platform successfully integrates 17 individual quantum devices onto a single chip, validating the repeatability of multi-nanotube placement within dense control topologies. IP Portfolio Integration & Scalable Fault-Tolerant Roadmaps The implementation of the Pick & Place protocol provides the baseline infrastructure required to execute C12’s comprehensive product roadmap published in April 2026. Managed by Co-Founder and Chief Technology Officer Matthieu Desjardins, the long-term hardware strategy charts four consecutive quantum processing generations—scaling from Aïdôs in 2027 to the 100,000 physical qubit Panopeia system by 2033—designed to transition early logical operations into universal fault tolerance. This fabrication milestone complements a broader structural layout: material foundations validated through a Nature Communications publication, specialized quantum error correction modeling secured via an integration of QC Design’s Plaquette platform, and automated algorithmic synthesis provided through a software partnership with Classiq.
