C12 has launched a new technology for manufacturing carbon nanotube quantum processors, significantly speeding up production times.
C12, a startup based in Paris, has introduced its innovative Pick & Place technology for the precise manufacturing of quantum processors using carbon nanotubes.
This technique facilitates the placement of individual nanotubes onto silicon chips with micrometer accuracy in controlled environments such as a vacuum. A significant advantage of this method is the capability to pre-screen and select nanotubes prior to their integration, which effectively tackles the issue of variability in qubit performance.
The company reports that by refining and partially automating this process, it has successfully assembled 50 quantum devices in just the past four weeks, a stark improvement compared to the year-long timeframe needed to produce a similar quantity in 2025.
Additionally, the Pick & Place technology enables the construction of multi-qubit configurations. C12 showcased a High-Density chip featuring 17 quantum devices integrated onto a single substrate.
“We have adapted advanced semiconductor packaging principles to the nanoscale. This opens up possibilities for mass production of quantum chips,” stated Matthieu Desjardin, C12's CTO.
This advancement aligns with C12's strategic plan, which was outlined in April 2026, targeting a progression from the initial logical qubit to systems with 100,000 physical qubits by 2033. The company underscores the importance of establishing a reliable manufacturing foundation to reach these ambitious objectives.
In related news, D-Wave Quantum announced on June 1 its intention to develop a fault-tolerant quantum computer featuring 100 logical qubits by 2032.
