Quandela, with its unique approach based on semiconductors and photonics, reveals an ambitious roadmap and an architecture that requires fewer integrated components than competing technologies. Its strategy focuses on developing industrial processes to address tomorrow’s challenges.

Paris, October 11, 2024 – Quandela, the European leader in photonic quantum computing, unveils its ambitions with the publication of its 2024-2030 technology roadmap. The company aims to achieve fault-tolerant quantum computing by 2030. To this end, Quandela intends to reach a major first milestone of achieving the first logical (error-free) qubits in 2025, before accelerating the scaling of quantum computing through quantum networking – connecting multiple quantum computers – by 2028.

A Complete Range of Services Around Quantum Computing

From its inception, Quandela has developed a strategy as a full-stack quantum player, offering a complete range of services to businesses and research communities: production of quantum computers, cloud access, training, and identification of use cases with industries. This ambition is fully reflected in the technology roadmap unveiled by the company, which should lead it to develop industrial processes capable of meeting tomorrow’s technological challenges and business issues by 2030. To achieve this, Quandela can rely on a major advantage of its integrated photonic technology, which is particularly efficient as it requires millions of times fewer components than competing photonic technologies.

Computing Capacity: Towards 50 Logical Qubits in 2028

Quandela’s success depends on increasing the power of its quantum processors, with a 25-fold multiplication (from 400 to 10,000) of quantum operations per second (QOPS). The company, which aims to achieve the first logical (error-free) qubits in 2025, should obtain 50 of them by 2028. By 2030, Quandela aims to operate at the scale of hundreds of logical qubits.

Increased Industrial Capacity with a Second Quantum Computer Factory

In terms of industrialization, Quandela aims to be capable of assembling 4 quantum computers per year starting in 2025, then launch a second quantum computer factory in 2027, before reaching the stage of large-scale assembly of error-corrected quantum computers from 2028.

Supporting Application Developers

For application developers, Quandela aims to launch its general-purpose quantum computing libraries in 2028. In terms of software and algorithms, Quandela intends to boost AI applications by developing QPU-GPU hybridization from 2025, before developing compilers and decoders dedicated to error correction in 2027.

Selected for the Proqcima Program

In spring 2024, Quandela was selected as one of five quantum players for the PROQCIMA program operated by the French Defense Procurement Agency (DGA) as part of the France 2030 program. This program aims to have two French-designed universal quantum computer prototypes by 2032. Quandela is fully confident in its ability to be one of the two companies selected at the end of this multi-year program.

A Roadmap Respected So Far by Quandela

This ambitious agenda is part of a favorable history for Quandela, as the company has so far always met, and sometimes even exceeded, the objectives it set for itself in recent years. Quandela was the first European player to make its quantum computers available in the cloud and to sell and deploy a quantum computer to a private client. The company was also selected in September by the EuroHPC Joint Undertaking to deliver a quantum computer, which will be hosted in France.

“This technology roadmap positions Quandela among the very few global players offering a clear and solid path to the universal quantum computer. The roadmap is ambitious and credible given the objectives already achieved since the company’s founding in 2017, and the excellent performance in the ratio between achieved objectives and deployed financial resources. The agenda unveiled today should allow Quandela, year after year, to ensure its technological and industrial ramp-up in order to perfectly succeed in the quantum transition, which is shaping up to be a strategic and unavoidable issue for companies and even states by the end of the decade,” says Niccolo Somaschi, co-founder and CEO of Quandela.

WITTENSTEIN and Quandela underscore European innovative strength

Two leading technology companies from Germany and France are joining forces to help shape Europe’s future in quantum computing: attocube systems GmbH, a company of the WITTENSTEIN group and specialist in nanotechnology, and Quandela, a pioneer in photonic quantum computer technology. The companies have been working together on the development of the European quantum computer Lucy. Representatives of the owners, Management Board and senior management of the WITTENSTEIN group took advantage of a visit to Paris to meet with the Quandela team and assess the status of the joint project.

Lucy is no ordinary computer. It is based on light particles – known as photons – and belongs to a new generation of quantum computers that are opening up completely new possibilities in areas such as artificial intelligence, cyber security, and materials research. The quantum computer was commissioned by the European High Performance Computing Joint Undertaking (EuroHPC JU) following a competitive tender process won by the Quandela-attocube consortium.

The collaboration between Quandela and attocube demonstrates how European companies can work together to achieve technological excellence. While Quandela is developing the photonic quantum platform, attocube is supplying high-precision cryogenic systems—technology that generates the extremely low temperatures required for quantum processes.

The visit to France focused on technical progress and system integration. The participants discussed how quantum and classical computers can be combined even more effectively in the future—for example, for hybrid applications in AI or complex simulations.

“Lucy is more than a technical project – she is a symbol of European innovation,” said Dr. Bertram Hoffmann, CEO of WITTENSTEIN SE. Niccolo Somaschi, co-founder and CEO of Quandela, added: “Lucy stands for technological excellence and for the common goal of making Europe a world leader in quantum computing.”

Lucy is scheduled to go into operation later this year. It will be based at the French supercomputer center CEA TGCC, where it will serve as the cornerstone of a sovereign European quantum ecosystem.
