C12 is asserting that it just lately raised an €18 million funding spherical ($19.4 million at at the moment’s alternate price). 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 based mostly 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 at the moment are totally based mostly on digital transistors. And we’ve change into actually good at making transistors smaller so we will pack extra transistors in a single chip. In consequence, computing energy has progressed at an exponential tempo over the previous 60 years.
And but, the present laptop structure has its limits. Even when corporations begin constructing greater knowledge facilities, some issues merely can’t be solved with conventional computer systems. It’s also unclear whether or not Moore’s regulation will stay legitimate within the years to come back.
That is the place quantum computer systems might show helpful.
“If we want to create a model — an exhaustive simulation of a chemical reaction — to know how new drugs are going to interact with our cells, that’s not possible with a conventional approach,” C12 co-founder and CEO Pierre Desjardins (pictured proper) informed TechCrunch.
“There are a whole host of optimization problems to be solved, whether in transport, logistics or manufacturing. They are impossible to run on a conventional computer because there will be too many variables, too many possible scenarios,” 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 known 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. “Today, training a large language model also means consuming an enormous amount of energy,” Pierre Desjardins mentioned. “And quantum is also a computing method that uses much less energy.”
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.
“Today, I think we are the only ones in the world to control this very special process, which involves putting a carbon nanotube on top of a silicon chip. And what’s absolutely fascinating is the scale. The diameter of a carbon nanotube is 10,000 times smaller than a human hair,” Pierre Desjardins mentioned.
Analysis groups working for large corporations like Google, IBM or Amazon are presently specializing in a unique course of. Most of them are utilizing superconducting supplies, comparable to aluminum, on high of a silicon substrate.
In accordance with C12, whereas this technique has led to early breakthroughs. Nonetheless, 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 running. Today, we produce about one chip a week, which we then test in our mini data center,” Pierre Desjardins mentioned. However don’t count on to see a quantum laptop simply but. “We are still really just validating fundamental elements,” 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 corporations, C12 has created an emulator known 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 a minimum of they are going to be able to hit the bottom working when quantum computer systems can be found.
“We are currently focusing on two verticals, the chemical industry and the energy industry. The chemical industry uses it to simulate chemical reactions and the energy industry uses it mainly for optimization problems,” Pierre Desjardins mentioned. 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; current 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 folks from 18 completely different nationalities working for C12 at the moment, together with 22 PhDs. With the just lately raised capital, C12 plans to signal extra partnerships with industrial companions. However the firm additionally has a analysis objective.
“The other goal is to carry out, for the first time, a quantum operation between two qubits that are located at a long distance from each other,” Pierre Desjardins mentioned. By lengthy distance, he means “tens of micrometers” from one another. It doesn’t appear to be a lot, however it is going to be key in relation to scaling quantum computing.
