Quobly’s vision of quantum computing

Pioneering. Disruptive. Scalable.
Quobly brings the performance of volume semiconductor manufacturing to the challenges of quantum.
Our vision

Quantum fabs will be familiar, not futuristic.

Our greatest
strength is what
we already know.
Our plan for scaling up Quantum

The semiconductor industry perfected its manufacturing processes over decades to get to where it is today.

At Quobly, we believe that borrowing the tried and tested processes that have been used to make billions of high-performance semiconductor devices is the fastest, most efficient way to scale a quantum processor in years, not decades.

We know how to transform electrons into
programmable silicon qubits.
Now we are going to make billions of them.

to qubit

a not-so-quantum leap

Why silicon makes sense for quantum

Today’s chip industry is the result of decades spent honing manufacturing processes to meet the needs of volume markets—a long and capital-intensive process. Quantum, on the other hand, will serve niche markets, making investment on such a massive scale hard to justify. We believe that leveraging existing semiconductor processes is the best way to achieve competitive per-qubit costs within a reasonable timeframe.

No quantum startup is closer to the semiconductor industry

Quobly’s team feels just as at home in a semiconductor fab as in a physics lab. In fact, the company’s founders are world-renowned quantum experts with proven out-of-the-lab track records in the semiconductor industry with market leaders like STMicroelectronics and the IBM Alliance. And Quobly’s wafer technology of choice, FD-SOI, was born in the company’s home city of Grenoble, France.

Quantum is a new computing paradigm

New AI models are pushing demand for computing resources—and costs—through the roof. Our quantum processing units—QPUs—can solve complex problems resource-efficiently. The impacts on AI, materials science, drug discovery, and energy systems could be huge. This is what we believe makes quantum so promising and exciting.

2022 Company launched

A spinoff of CEA-Leti and CNRS, quantum computing company Quobly was founded in European semiconductor hotspot Grenoble, France, in November 2022.

52 People on our team

Quobly's growing team is rapidly building a company and an entire ecosystem capable of getting its silicon quantum processor into fabs within the decade.

$21.5M Capital raised

Quobly completed a €19 million seed round and received a €2.5M EIC Transition grant in July 2023. This was the largest seed round of any European quantum startup at that time in terms of the amount of private equity invested.

A closer look at spin qubits on FD-SOI

We believe that a high-performance silicon substrate called FD-SOI, already used in many of the world’s smartphones, will help us overcome some of the major challenges to scaling up to millions of qubits.
