Q.ANT

Stop Cooling. Start Photonic Computing.

Q.ANT provides photonic accelerators for AI and high-performance computing, offering a scalable alternative to transistor-based systems. Its Native Processing Units (NPUs) perform mathematical operations directly on Thin-Film Lithium Niobate (TFLN) based photonic integrated circuits, enabling energy-efficient, high-performance co-processing for complex computational tasks.

Q.ANT was founded in 2018. Its European headquarters is in Stuttgart, Germany, where it operates its own TFLN chip pilot line with IMS CHIPS, and it maintains a U.S. office in Austin, Texas. The company secured Europe’s largest Series A for photonic computing in 2025 and introduced its second-generation processor the same year, now installed and running at leading scientific computing centers (Leibniz Supercomputing Center and Jülich Supercomputing Center) with its first commercial deployment at cloud and hosting partner IONOS planned for 2026.
