Photonic quantum startup QuiX Quantum has closed a €15 million ($17.5m) Series A funding round, co-led by Invest-NL and EIC Fund and with participation from PhotonVentures, Oost NL, and FORWARD.one.

The company said it will use the funds to help it deliver the world’s first single-photon-based universal quantum computer in 2026.

Founded in Enschede, the Netherlands, in 2019, the company claims it has become the “supplier of choice across Europe” for quantum processors. QuiX says its universal photonic quantum computer “leverages the principles of superposition, entanglement, and interference,” meaning they process information in “fundamentally different” ways from classical computers.

The processors are also built on silicon-nitride chips, which the startup says makes them highly scalable and allows them to operate primarily at room temperature, making them fully compatible with data center environments.

In 2022, QuiX sold both eight-qubit and 64-qubit photonic quantum computers to the German Aerospace Center (DLR QCI) and in 2024, began offering cloud access to its quantum systems.

“Our Series A funding round fuels our mission to further develop the core building blocks required for a fault-tolerant universal quantum computer,” says Dr. – Ing. Stefan Hengesbach, CEO of QuiX Quantum. “With our first-generation system in 2026, we will demonstrate universality by overcoming long-standing challenges in fast feed-forward electronics and single-photon sources. The next-generation system, planned for 2027, will focus on implementing error correction, a crucial step towards fault-tolerant systems capable of transforming industries such as chemical engineering, drug development, fraud detection, and advanced manufacturing.”
