SmaraQ Integrates Quantum Optics On-Chip to Advance Scalable Ion-Trap Quantum Computing

A new German research initiative, SmaraQ, is pioneering the integration of quantum optics directly onto chips, marking a major leap for the future of ion-trap quantum computers. The collaborative project, led by QUDORA Technologies alongside AMO GmbH and Fraunhofer IAF, is focused on developing ultraviolet (UV) photonic components specifically waveguides made of aluminum nitride and aluminum oxide that can be fabricated by lithography and built directly onto ion-trap chips. This innovation aims to replace the bulky, complex free-space optical systems currently used to control and read out ion qubits, clearing the path for more scalable, reliable, and compact quantum processors.

Currently funded through 2028 by the German Federal Ministry of Research, Technology, and Space, SmaraQ not only advances the technical frontier but also sets out to create a robust, Germany-based supply chain for next-generation quantum technologies. By miniaturizing optical delivery and control systems to the nanometer scale, the project expects to enable larger ion-trap architectures while strengthening Germany’s sovereignty and leadership in global quantum computing.
