Light Modulators Driving Quantum Innovation — •Enrico Vogt — QUBIG GmbH, Grillparzerstr. 6, 81675 Munich, Germany

Quantum technologies are rapidly advancing, with the potential to revolutionize fields such as secure communication, high-precision sensing, and quantum computing. A key enabler of this transformation is the ability to precisely control laser light using electro-optic (EOM) and acousto-optic modulators (AOM), which manipulate the frequency, amplitude, polarisation and phase of laser beams with high speed and accuracy. Traditionally reliant on bulky, alignment-sensitive setups, these modulators have now been redefined by a breakthrough at QUBIG that makes them compatible with surface-mount device (SMD) technology. This innovation dramatically reduces the size, complexity, and cost of advanced laser systems - paving the way for mass-producible, ultra-compact quantum devices. By bridging cutting-edge photonics with modern manufacturing, this innovation unlocks new opportunities for industrial deployment, global competitiveness, and strategic investment in the rapidly growing quantum economy. In this talk, the policy framework conditions that could promote the successful implementation of this technology in Germany are also mentioned.
