Belenos

Digital Quantum Computer

The world’s most powerful photonic quantum computer

– First deployement May 2025

Quandela announces the launch of Belenos, the world’s most powerful photonic quantum computer. This is a key milestone in the company’s Roadmap 2030, which is on track to meet its ambitious timeline.

Accessible to commercial and industrial partners in the cloud, Belenos offers 4,000 times more computing power than the previous generation, unveiled just two years ago with the launch of the first photonic quantum computer in the cloud. The first fully integrated version will be delivered in a supercomputer at the end of 2025.

Belenos is now available in the cloud to more than 1,200 researchers and partner companies in 30 countries.
