C12 Introduces Nanoassembly Process for Carbon Nanotube Quantum Chips

AI-summarised brief · reviewed before publication

C12, a Paris-based quantum computing company, has introduced a proprietary nanoassembly process called Pick & Place. This technology enables the transfer of individual carbon nanotubes onto silicon chips with high precision, addressing qubit variability and improving manufacturing control. The process has significantly increased production throughput and supports the integration of higher-density multi-qubit chip architectures. Two setups are operational in C12's Paris laboratory, and the company claims to be the only one capable of electrical prescreening at the qubit level.

💡 Why It Matters

  • · The Pick & Place technology is a crucial step towards scalable manufacturing of carbon nanotube quantum processors, addressing one of the hardest challenges in quantum hardware manufacturing: qubit variability.
  • · By enabling reproducible manufacturing, C12 is one step closer to achieving its ambitious roadmap, which targets four processor generations from 2027 to 2033, scaling from a first logical qubit to over 100,000 physical qubits at utility scale.
