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 [...] The post C12 Automates Pick & Place Nanoassembly to Standardize Carbon Nanotube Qubit Fabrication appeared first on Quantum Computing Report .

Why this matters
Why now

The quantum computing sector is rapidly maturing, driving the need for standardized and scalable fabrication methods to move beyond prototype stages.

Why it’s important

This development addresses a critical manufacturing bottleneck in quantum hardware, potentially accelerating the commercial viability and scaling of carbon nanotube-based qubits.

What changes

The ability to precisely place carbon nanotubes on quantum circuits decouples difficult growth processes from sensitive lithography, directly improving yield and enabling more complex qubit designs.
