C12 is saying that it lately raised an €18 million funding spherical ($19.4 million at right this moment’s trade fee). Initially based in 2020 as a spin-off from the Physics Laboratory of the École Normale Supérieure, the corporate has been engaged on a singular course of to create quantum computer systems primarily based on carbon nanotubes.
Whereas the idea of quantum computing isn’t new, it’s nonetheless very a lot a piece in progress. Many scientific groups have been approaching this subject from completely different angles. The objective is to create a quantum laptop at scale that may execute calculations with a low quantity of errors.
However wait, why do we want quantum computer systems within the first place? Computer systems as they exist right this moment are totally primarily based on digital transistors. And we’ve develop into actually good at making transistors smaller so we are able to pack extra transistors in a single chip. Because of this, computing energy has progressed at an exponential tempo over the previous 60 years.
And but, the present laptop structure has its limits. Even when firms begin constructing greater information facilities, some issues merely can’t be solved with conventional computer systems. Additionally it is unclear whether or not Moore’s regulation will stay legitimate within the years to come back.
That is the place quantum computer systems may show helpful.
“If we wish to create a mannequin — an exhaustive simulation of a chemical response — to know the way new medication are going to work together with our cells, that’s not potential with a traditional strategy,” C12 co-founder and CEO Pierre Desjardins (pictured proper) informed TechCrunch.
“There are a complete host of optimization issues to be solved, whether or not in transport, logistics or manufacturing. They’re unattainable to run on a traditional laptop as a result of there can be too many variables, too many potential eventualities,” he continued.
Matthieu Desjardins, his brother, has a PhD in quantum physics and acts because the CTO of the corporate. Sooner or later in our dialog, Pierre Desjardins even referred to as his brother a “scientific genius.”
And since it’s 2024, there’s even an AI angle that ought to persuade you that quantum computing analysis is necessary. “Right this moment, coaching a big language mannequin additionally means consuming an unlimited quantity of vitality,” Pierre Desjardins stated. “And quantum can be a computing technique that makes use of a lot much less vitality.”
How you can construct a quantum laptop
C12 says the 2 key variations with the opposite groups engaged on quantum computer systems are that it makes use of a unique materials — carbon nanotubes — and it has a particular manufacturing course of — a nano-assembly course of that’s now patented.
“Right this moment, I believe we’re the one ones on the planet to manage this very particular course of, which includes placing a carbon nanotube on prime of a silicon chip. And what’s completely fascinating is the size. The diameter of a carbon nanotube is 10,000 instances smaller than a human hair,” Pierre Desjardins stated.
Analysis groups working for large firms like Google, IBM or Amazon are presently specializing in a unique course of. Most of them are utilizing superconducting supplies, reminiscent of aluminum, on prime of a silicon substrate.
In keeping with C12, whereas this technique has led to early breakthroughs. Nevertheless, utilizing aluminum isn’t going to work at scale as a consequence of interferences as you begin including extra qubits. Whereas quantum isn’t mature but, C12 believes it’s engaged on next-generation quantum computing in comparison with these aluminum-based processes.
The corporate has arrange its first manufacturing line in a basement close to the Pantheon in Paris. On this facility, they manufacture carbon nanotubes, management these tubes after which combine them with the silicon substrate.
“It’s now up and working. Right this moment, we produce about one chip every week, which we then check in our mini information heart,” Pierre Desjardins stated. However don’t anticipate to see a quantum laptop simply but. “We’re nonetheless actually simply validating basic parts,” he added. The corporate is specializing in chips with one or two qubits for the second.
Emulating quantum
As analysis and improvement work progresses, the C12 crew can be engaged on its enterprise ecosystem. Like many quantum firms, C12 has created an emulator referred to as Callisto. Emulators let builders write and run some quantum code on a classical laptop.
They’re not going to get the outcomes they’d get with a quantum laptop, however no less than they are going to be able to hit the bottom working when quantum computer systems can be found.
“We’re presently specializing in two verticals, the chemical trade and the vitality trade. The chemical trade makes use of it to simulate chemical reactions and the vitality trade makes use of it primarily for optimization issues,” Pierre Desjardins stated. Particularly, the startup has a partnership with Air Liquide.
And if we return to the funding spherical, Varsity Capital, EIC Fund and Verve Ventures are investing in it; present traders 360 Capital, Bpifrance’s Digital Enterprise fund and BNP Paribas Développement are additionally collaborating as soon as once more on this spherical.
There are 45 individuals from 18 completely different nationalities working for C12 right this moment, together with 22 PhDs. With the lately raised capital, C12 plans to signal extra partnerships with industrial companions. However the firm additionally has a analysis objective.
“The opposite objective is to hold out, for the primary time, a quantum operation between two qubits which might be positioned at a protracted distance from one another,” Pierre Desjardins stated. By lengthy distance, he means “tens of micrometers” from one another. It doesn’t seem to be a lot, however it will likely be key with regards to scaling quantum computing.
