Company
Taking quantum
out of the lab.
SpectralFlow SAS is a European deep-tech company designing, patenting and industrialising NV-diamond quantum sensors — room temperature, chip-scale, sovereign.
Vision
Quantum sensing should work in the field, not just the lab.
The most powerful quantum sensors today are trapped behind cryostats, shielded rooms and optical tables. We believe the technology that wins is the one you can put on a drone, a hull or a satellite — rugged, low-power and ready to ship.
We follow an “NVIDIA model”: design the sensor, the firmware and the calibration; outsource the fab. That keeps a lean team focused on the defensible intellectual property while scaling through partners.
Sovereignty thesis
Critical sensing, built in Europe.
Positioning and sensing in contested environments are strategic capabilities. They should not depend on foreign supply chains or signals anyone can switch off. SpectralFlow builds a sovereign, European alternative — designed, patented and owned on the continent.

Alexandre Papa
SpectralFlow was founded by Alexandre Papa, who moved from a finance and corporate background into deep tech, dedicating the last several years to quantum sensing. That path shapes how the company is run: rigorous on capital and execution, obsessive about the underlying physics.
The conviction is simple — Europe has the science to lead in quantum sensing, and what it needs is a team that turns that science into manufacturable, field-ready products.

Scientific & industrial partners
We work with leading European research institutions and an industrial network across the diamond, photonics and navigation value chains. We name partners publicly only once collaborations are confirmed and cleared to share.
