SOUTHERN FRANCE, October 18, 2023 – An international partnership has become formed, spearheaded by French quantum tech firm PASQAL, with the shared vision of laying the groundwork for the future of photonic quantum computing. This potentially revolutionary venture, backed by the European Innovation Council’s Pathfinder-2023 grant, brings together leading academic and industrial entities.

The partnership, including the likes of Sorbonne Université in France, Pixel Photonics GmbH from Germany, Spain’s Institute of Photonic Sciences, and the French Institut d’Optique Théorique et Appliquée, will focus on harnessing the immense potential of neutral atom technology to craft a quantum processor, with light serving as the primary vehicle for quantum data.

Light’s innate capacity to transport significant data over extended ranges with minimal loss—especially at ambient conditions—makes it an ideal candidate for quantum computing scalability. However, the inherent non-interaction of light particles, photons, poses a considerable challenge in designing quantum circuits, as interactions are vital for operations.

Addressing this challenge, the consortium, dubbed PANDA, will delve into creating a quantum computer that exploits the interaction between photons and a unique arrangement of neutral atoms. Leveraging PASQAL’s advanced technique, which uses highly precise lasers known as optical tweezers, these neutral atoms can be meticulously organized into versatile 2D and 3D matrices.

Loïc Henriet, CTO of PASQAL, expressed his enthusiasm, stating, “Teaming up with renowned photonics experts, we’re poised to propel quantum computing to new horizons. We firmly believe that our naturally sourced atoms will play an invaluable role in this initiative.”

A cutting-edge technique under PANDA’s purview aims to craft novel states of light with unmatched efficiency!

This will be achieved by combining collective expertise in atomic ensemble research, quantum light study, high-efficiency light detection, and breakthroughs in nano-photonics.

Pixel Photonics’ CTO, Wladick Hartmann, shared his insights: “Our goal to systematically create novel light states will pave the way for revolutionary quantum computing frameworks. We’re eager to contribute our advancements in photon detection to this groundbreaking approach.”
