Quobly and SiPearl team up on a sovereign European CPU and quantum processor system

French quantum company Quobly has signed a memorandum of understanding with European chip designer SiPearl, The Quantum Insider reports. Quobly builds silicon spin qubit quantum computers aimed at industrial scale. SiPearl designs high performance, energy efficient European CPUs. Together they want to build a sovereign European quantum computing system

The first phase is practical. SiPearl's first generation Rhea1 CPU and its Seine reference server will be integrated with a Quobly quantum processor system. That work sits inside the development of Quobly's Alloy product line, and it will test whether the two technologies can work in one system architecture. Later phases would optimise hybrid HPC and quantum workloads and look for ways to design future products together

The two companies will also coordinate on European tenders. That includes possible joint bids under the Chips Joint Undertaking quantum programmes. No financial terms were given, and the agreement is non exclusive. So both firms are free to work with others at the same time

Quobly CEO and co-founder Maud Vinet said building scalable quantum computers also means building the classical computing environment around them. SiPearl's founder and CEO Philippe Notton said the two share the same vision on the need for a European hardware ecosystem for sovereign computing. He called the deal another significant milestone in building that ecosystem. Sovereignty is clearly the word of the moment in European tech

I think the logic is sound. Every quantum computer needs a lot of classical computing next to it for control, error correction and running hybrid algorithms. If Europe wants a machine that does not depend on US or Asian chips, the CPU side matters as much as the qubits. Silicon spin qubits also fit nicely with the idea of using existing chip making know how

Does Europe need its own full quantum stack, or is that wishful thinking? And how do you rate silicon spin qubits against the other approaches?

Grenoble is the hub for this. Quobly spun out of CEA-Leti and CNRS work there, and the area has a long history in silicon research. France has been quietly building one of the strongest quantum scenes in Europe

Pasqal, Alice and Bob, Quandela and now this. The research culture there is very strong

Joint bids for EU tenders is the most telling part. European funding often rewards partnerships between member states

A French quantum firm and a French CPU firm teaming up fits that perfectly. It is as much about winning contracts as building tech. Brussels likes a good partnership story

[Isaac85]

Sovereignty is a nice word, but the market is global. European firms still buy equipment from everywhere, including the cryogenics and lasers

A fully European stack is a long way off. Small steps like this help, though

Classical control is massively underrated. People talk about qubit counts, but the electronics and computing needed to run error correction in real time are enormous

Having a CPU designed with that in mind could be a real advantage. Good to see someone thinking about it early

Error correction needs decisions made in microseconds. That puts enormous demands on the classical side. Getting the CPU right could make or break a system

Silicon spin qubits are my favourite long shot. They are tiny, which means you could fit huge numbers on a chip. The fidelities have improved a lot in the last few years. Quobly and Diraq are the two names to watch

Their big advantage is that existing fabs could make them. That is a huge head start if it works out
