The EuroQCS-France consortium, led by GENCI and CEA, is pleased to announce that European researchers can now access a 12-qubit Quandela photonic quantum computing system remotely. This exciting development allows European users to begin programming and testing their applications on a real photonic quantum computer, months ahead of the anticipated deployment at TGCC (CEA’s computing center) of the on-premise Lucy system in the end of 2025. They can be supported by experts from a High-Level Support Team to port their applications onto the photonic quantum computer.

The EuroQCS-France consortium and the selection of Quandela as supplier by the EuroHPC Joint Undertaking (JU)

In 2024, EuroHPC JU selected a consortium formed by Quandela and its German partner attocube systems AG as the supplier of the photonic quantum computing technology as part of the EuroQCS-France initiative. This collaboration is set to pave the way for a new era in quantum computing across Europe, enhancing research capabilities and advancing the quantum ecosystem.

In November 2024, on the occasion of SC24, EuroQCS-France officially announced the provision of early remote access to a 6-qubit Quandela photonic quantum computer for the European open research community. Now, users will be able to run their code on a remote 12-qubit quantum computer, with the same design as the upcoming Lucy system. This provides a unique opportunity to engage with a photonic quantum computer, allowing open research communities to get hands-on experience before the Lucy system is fully installed and operational at TGCC in 2025.

Key Benefits for European Researchers

· Early Access: Open research communities can begin preparing their code using Perceval now, the Quandela programming and emulation environment deployed on the Joliot-Curie supercomputer, and run their applications on a remote 12-qubit photonic quantum computer similar to the targeted Lucy system.

· No Wait for Deployment: Users will not have to wait for the installation of Lucy to access a real quantum computing system, allowing them to start experimenting and testing their applications immediately.

· Expert Support: A High-Level Support Team will assist users in porting their applications onto the photonic quantum computer, ensuring that researchers can fully leverage the technology.

· Training Sessions: GENCI/CEA and Quandela will be offering specialized training on hybrid HPC-QC programming schemes, helping users prepare for the integration of Lucy with Joliot-Curie.

How to Access the Remote System

The process to access the remote Quandela system will be outlined by CEA, and interested researchers can apply for access through the designated channels. More details will be provided shortly.

Looking Ahead

EuroQCS-France is part of the broader European effort to build a diverse, pan-European hybrid HPC/QC infrastructure. Lucy, the 12-qubit photonic quantum computer, will soon join other cutting-edge quantum systems across Europe, each based on different hardware technologies. These systems include scalable superconducting qubits (Euro-Q-Exa), star-shaped superconducting qubits (LUMI-Q), trapped ions (EuroQCS-Poland), quantum annealing (EuroQCS-Spain), neutral atoms (EuroQCS-Italy), each system providing unique capabilities and research opportunities.

In the coming months, as the Lucy system’s deployment approaches, this early access will be crucial in ensuring that European researchers are well-prepared to take full advantage of the system’s capabilities.

GENCI/CEA and Quandela will be organizing training sessions on hybrid HPC-QC programming schemes leveraging photonic quantum computing to anticipate the integration of Lucy with Joliot-Curie.

_______________________________________________________________________________

Paris, February 7, 2025 – Quandela, the European leader in photonic quantum computing, announces a major breakthrough for the sector in a scientific paper¹ describing a reduction by a factor of 100,000 in the number of components required for fault-tolerant calculations. Quandela’s hybrid approach, based on a technology that generates photonic qubits with unprecedented efficiency from artificial atoms (semiconductor quantum emitters), should enable the company to accelerate the scaling-up of its quantum computers.

A photonic approach promising for error-correction and scaling challenges

Fault-tolerant – error-free – quantum computing is crucial for the correct execution of the most impactful quantum algorithms, such as prime number factorization, linear system solving and chemical simulations. It is these algorithms that enable the most valuable use cases that “classical” computers cannot solve, notably in the energy, pharmaceutical, chemical and defense sectors.

Among all quantum platforms, the photonic platform appears particularly promising for achieving fault tolerance, thanks to the unique ability of photons to :

carry quantum information almost infinitely

interconnect quantum processors via commercial optical fibers, as is the case with today’s largest network-connected computers.

Interconnection between quantum processors is essential, in the long term, to extend the computing power of quantum computers – in a similar way to today’s networked supercomputers – whatever the platform in question. Photonic technology therefore inherently possesses the modularity that is absolutely essential for scaling up and implementing error-correction protocols.

However, since photon loss is the main source of error in the photonic approach, the high performance of these quantum computers implies high optical transmission of the components, i.e. a high flow of photons through all the components. The big challenge is therefore to reduce the number of components (“resources”) in order to achieve the high optical transmission needed to manipulate and correct a large number of qubits, and thus achieve the high-impact calculations that outperform conventional computers.

Quandela’s approach 100,000x less resource-intensive than other photonic competitors

To meet this challenge, Quandela has just reported a groundbreaking scientific result that presents a method for reducing resource requirements by a factor of 100,000 compared with the photonics-only approach adopted and developed by other photonic quantum computing players in the USA and Canada.

At the heart of this result lies the core technology of Quandela’s processors, based on semiconductor quantum emitters that generate photonic qubits with world-leading efficiency. Thanks to its hybrid approach, which uses these emitters both as photon generators and as qubits (by exploiting the spin of one of the emitter’s electrons), Quandela sets itself apart from other photonic competitors.

Where a purely photonic approach would require around a million components to generate one logic qubit, the research team, led by Quandela’s Chief Research Officer Shane Mansfield, demonstrates that Quandela’s approach requires just 12, i.e. 100,000 (= 10^5 times ) less. This approach also greatly relaxes the optical transmission requirements of the components, and therefore the performance required for error correction.

Significant reduction in energy consumption

This considerable gain, which promises to reach the error-correction regime much more quickly, also makes it possible to drastically reduce the platform’s manufacturing costs and energy consumption. Quandela predicts a much lower power consumption than existing quantum platforms. In practice, while today’s large-scale high-performance computing centers consume around 20 MW, and cloud hyperscalers dedicated to AI require around 2 MW, Quandela’s largest quantum computer should keep its power consumption below 1MW. Quandela’s computers are therefore positioned as the solution for increasing the computing power needed by industry worldwide, without increasing energy consumption.

“This breakthrough marks an important milestone for error-correcting computing with the photonic platform. By drastically reducing the resources required while maintaining the intrinsic advantages of the photonic approach, we are paving the way for the realistic industrialization of fault-tolerant quantum computing. Our unique hybrid approach demonstrates Quandela’s ability to significantly accelerate the scale-up of quantum computers, a crucial issue for the entire industry”, comments Niccolo Somaschi, co-founder and CEO of Quandela.
