Pasqal teams for photonic quantum processor
Pasqal has teamed up with pan-European researchers on a photonic quantum computer powered by neutral atom technology.
Pasqal is working with Sorbonne Université, Pixel Photonics in Germany, the Institute of Photonic Sciences (ICFO) in Spain and Institut d’Optique Théorique et Appliquée (IOTA) in France with a Pathfinder-2023 challenge grant from the European Innovation Council.
The PANDA consortium aims at building the foundations of a photonic quantum computer through the interaction between photons with a specially ordered assembly of neutral atoms. The Pasqal architecture uses highly focused lasers called optical tweezers to manipulate neutral atoms and arrange them in 2D and 3D arrays of any configuration, mapping well to a photonic quantum computer architecture.

The project is coordinated by the Multimode Quantum Optics group at Sorbonne Université. This will use neutral atoms to develop the foundations of a quantum processor that will use light as the carrier of quantum information, using continuous variable quantum computing.
The technique under development by the consortium will enable them to manufacture exotic states of light with unprecedented efficiency by putting together their expertise in engineering and studying both atomic ensemble and quantum light. Combining with novel high-efficiency light detection with advances in nano-photonics, the PANDA partnership will develop the building blocks of photonic quantum computing.

“As leaders in neutral atoms quantum processing, we are excited to be part of this consortium. Innovations to our technology will help push forward quantum computing, together with experts in photonics. We are convinced that our atoms, provided by nature, will be optimal in this undertaking,” says Loïc Henriet, CTO at PASQAL.
Wladick Hartmann, CTO Pixel Photonics: “Providing a toolbox for the deterministic creation of exotic states of light will enable new and exciting quantum computing schemes. We are thrilled to provide the necessary innovation in photon detection to enable this new and exciting approach.”
“This project is very exciting scientifically, as it addresses one of the main bottlenecks of the otherwise very promising platform of quantum computing with non-classical light,” says Nicolas Treps, Professor at Sorbonne Université, Multimode Quantum Optics group, and coordinator of the project.
Pixel Photonics (PIX) is a nanophotonics SME founded in 2021 as a spin-off from WWU Münster to commercialize highly-scalable single-photon detectors. Applications for Pixel Photonics’ technology range from optical quantum computing, quantum key distribution, and microscopy to metrology and sensing.
