Insider Brief

C12 has unveiled its proprietary Pick & Place nanoassembly process, designed to transfer individual carbon nanotubes onto silicon chips with high precision for quantum processor manufacturing.

The company said the process enables preselection and qualification of carbon nanotubes before integration, helping address qubit variability and improve manufacturing control.

C12 reported that the new approach has significantly increased production throughput and supports the integration of higher-density multi-qubit chip architectures.

PRESS RELEASE — C12, a Paris-based quantum computing company developing carbon nanotube spin qubit processors, today announced its proprietary Pick & Place nanoassembly technology: a custom-built, patented nanoassembly method developed entirely in-house to transfer individual carbon nanotubes onto silicon chips with micrometric precision, in controlled vacuum or inert atmosphere conditions. Two setups are now operational in C12’s Paris laboratory.
