Q.ANT Expands to U.S. and Appoints Former IBM Executive as CTO

Q.ANT Expands to U.S. and Appoints Former IBM Executive as CTO Q.ANT, a Stuttgart-based developer of photonic computing hardware, has announced the opening of its U.S. headquarters in Austin, Texas. To lead its North American operations and global technology strategy, the company has appointed semiconductor veteran Bruno Spruth as Chief Technology Officer. Spruth joins Q.ANT from IBM, where he recently served as Vice President of Power Processor Development, overseeing high-performance computing architectures. The expansion aims to provide U.S. hyperscalers and data centers with an energy-efficient alternative to silicon-based accelerators. Q.ANT’s technology utilizes Native Processing Units (NPUs) built on a Thin-Film Lithium Niobate (TFLN) platform. By executing mathematical operations directly in the optical domain, the company reports its processors can achieve up to 30 times the energy efficiency and 50 times the performance of conventional transistors for specific AI and high-performance computing (HPC) workloads. Technical Implementation and Production Q.ANT’s systems are designed for “plug-and-play” integration into existing infrastructure: Form Factor: The Native Processing Server connects via standard PCIe interfaces, allowing it to operate as a co-processor alongside traditional CPUs and GPUs. Operational Requirements: Unlike many quantum or advanced computing components, Q.ANT’s photonic chips operate at room temperature, eliminating the need for specialized cryogenic cooling. Manufacturing: The company operates its own TFLN chip pilot line in collaboration with IMS Chips in Stuttgart and has expressed intent to localize chip manufacturing in the U.S. as it scales. Commercial Milestones and Funding In 2025, Q.ANT became the first company to deploy a commercial photonic processor in a live production environment at the Leibniz Supercomputing Centre (LRZ) in Germany. The processors are currently utilized for climate modeling, medical imaging, and fusion energy research. The U.S. move follows a $80 million Series A funding round supported by a broad group of investors, including Duquesne Family Office, Hermann Hauser, imec.xpand, and TRUMPF. Over the next six months, the company plans to grow its Austin-based team to 20 employees, focusing on software development, photonics, and digital system design.
