Launch of Siquance, a start-up by CEA Leti and CNRS dedicated to quantum computing

Siquance, a spin-off from CEA and CNRS, was officially launched on November 29th in Grenoble. The ambition of its three co-founders is to make it a leader in universal quantum computing by developing and commercializing a large-scale universal quantum computer based on microelectronic technologies, exploiting the capabilities of semi-European driver producers.

Quantum computing should make it possible to solve complex equations, currently beyond the reach of conventional computers, and this up to 1 billion times faster, reducing energy consumption. It addresses a variety of strategic and/or cutting-edge industrial sectors: healthcare, engineering, meteorology, finance, etc. Disruptive, it offers an opportunity for Europe to restore the balance of power with the United States and China, which are vying for supremacy in this area.

Although surpassed by the last two, which invest massively in quantum technology, France has undeniable advantages in this field: excellent research, Nobel prizes, quantum simulators by Atos, Prometheus, first photonic qubit generator by Quandela, quantum information processors by Pasqal …

CEA has been exploring the quantum field for more than thirty years, it is present throughout the quantum computing value chain, from materials to algorithms, passing through integration in high-performance computing centers. Alongside the CNRS and INRIA, it occupies a central place, contributing to the development of scientific knowledge and the mastery of the main quantum technological axes, but also through the reinforcement of synergies between emblematic industries, research organizations, universities and start-ups.

Jean-Philippe Bourgoin, head of CEA’s quantum program, says:

“CEA is leading a large-scale program in quantum technologies, with the aim of providing the essential advances for their development, in particular in quantum computing. It also involves anticipating the information-processing revolution that will accompany its deployment. As a historic player in quantum and semiconductor research, we are delighted to see our scientific advances, our technology building blocks and working together with the CNRS, being at the root of new deeptech companies in this very challenging field. of industrial and strategic sovereignty”.

To be at the forefront of French and European sovereignty in the field of quantum computing.

Created by Maud Vinet (CEO, CEA, ERC laureate), Tristan Meunier (CTO, CNRS, ERC laureate) and François Perruchot (COO, CEA), international experts in silicon technologies, quantum engineering and strategic marketing, Siquance is based built on years of research at CEA and CNRS, where its founders have been working together for six years and was the winner of the 2022 I-lab Grand Prize.

The start-up, strongly supported by CEA and CNRS, present in its capital, benefited from its R&D skills and capabilities, its intellectual properties, its technological means as well as its solid ecosystems that cover all the challenges of quantum technologies , from basic research to industrialization.

It aims to develop a silicon-based quantum computer, that is, based on the same technologies as standard integrated circuits. The main technological advance is based on the transformation of a transistor, the basic unit of classical calculation, into a quantum bit, the basic unit of quantum calculation. Together, these quantum bits will form a new type of computer, capable of solving many problems currently inaccessible to conventional computers.

Maud Vinet said:

“Thanks to the industrial sector of semiconductors and quantum computing that allows to approach all areas of the industry, Siquance wants to quickly establish itself and establish itself in a world market that in the long term aims to create a value of several hundred billion euros for all these areas”.

Within the scope of an R&D program with CEA and CNRS, two joint laboratories will be created, forms of collaboration between public research and companies.

Jean-Luc Moullet, Deputy Director General of Innovation at CNRS, concludes:

“The CNRS continues its strategic focus on the quantum area with the creation of Siquance. We are pleased to contribute, together with another research organization, to the emergence of a new important player in the sector in France. We are confident in the potential of our ecosystem to reproduce a similar partnership approach, up to the challenges of our country’s technological and industrial sovereignty”.
