Nanotube or nano-boast?
Pick and Place: Carbon Nanotube Nanoassembly Process
Tiny tube, giant brag? Fans cheer while skeptics roast the hype
TLDR: C12 says it has found a faster, more reliable way to place tiny carbon tubes onto quantum chips, a key step toward building future ultra-powerful computers. Commenters were amused but skeptical, joking about the dramatic sales pitch and asking for real close-up proof instead of big claims.
A French quantum startup says it can now pick up and place single carbon nanotubes—ultra-tiny strands far thinner than a human hair—onto computer chips with astonishing accuracy. In plain English: it’s trying to make one of the fiddliest parts of future quantum computers less chaotic and more repeatable. C12 says this new method massively speeds things up too, jumping from 50 devices in a whole year to 50 in just four weeks, and it has squeezed 17 quantum devices onto one chip.
But the real show was in the comments, where the community instantly split into two camps: “wow, that’s impressive” and “okay, but calm down with the marketing.” One of the funniest reactions came from a commenter deadpanning that placing something with “hair-on-Paris” precision sounded “very easy, honestly.” That joke basically set the tone: admiration mixed with heavy side-eye. Another reader went straight for the corporate buzzwords, poking fun at calling 17 devices “high density” and treating “50 devices in four weeks” like a blockbuster flex. Translation: cool science, but the victory lap may be a little early.
Then came the design critics. One commenter wanted actual proof—show us the nanotubes!—instead of generic lab imagery, even suggesting C12 spell out its own logo with the tiny tubes. It’s classic internet energy: if you say you can do nano-magic, people want receipts, memes, and maybe some arts and crafts. The vibe is clear: promising breakthrough, but the crowd wants less sizzle and more close-ups.
Key Points
- •C12 announced Pick & Place, a patented nanoassembly process for placing individual carbon nanotubes onto quantum chips with micrometric precision.
- •The company says the process decouples nanotube growth from chip fabrication, improving flexibility, modularity, and control over qubit variability.
- •C12 states that Pick & Place enables preselection and qualification of individual carbon nanotubes before integration, including qubit-level electrical prescreening.
- •C12 reports assembling 50 devices in the last four weeks with the new streamlined, partially automated process, compared with the same number during all of 2025 under the previous method.
- •The announcement supports C12's roadmap from Aïdôs in 2027 to Panopeia in 2033, alongside cited progress involving Nature Communications, QC Design, and Classiq.
