Q

Dutch photonic-hardware company spun out of the University of Twente in 2019. Builds reconfigurable photonic processors on low-loss silicon-nitride integrated waveguides — universal interferometer meshes used as the linear-optical core of a photonic quantum computer. The flagship 20-mode silicon-nitride processor reports ~2.9 dB loss and >90% transformation fidelity across its 20 programmable modes. Sells processors as modules and as full single-photon systems to academic and industrial customers. Closed a EUR 15M Series A in July 2025 to deliver a first-generation universal single-photon quantum computer.

  • positioning — User's brief described the platform as "lithium-niobate-on-insulator"; QuiX's verified product line is silicon-nitride. Lithium-niobate not confirmed in vendor materials; treating the brief as a slip and grounding to silicon-nitride per the vendor's own product page.
  • milestones[Cisco partnership] — Brief referenced a Cisco partnership; not found in search results and omitted rather than fabricated.
  • milestones[Q-bird partnership] — Brief referenced a Q-bird partnership; not surfaced by search. Q-bird (also a Dutch quantum-startup) plausibly collaborates with QuiX given the geographic / ecosystem overlap, but no source verified in this run.
