Magnolia Quantum Sensing provides the world’s first optical quantum sensor for direct magnetic field measurement in MRI. Our EXAAQ technology removes uncertainty at the heart of image formation, enabling faster, more reliable, and more affordable medical imaging. Based on more than eight years of research at the Niels Bohr Institute and the Danish Research Centre for Magnetic Resonance, Magnolia QS was founded in late 2025 to transform MRI through quantum sensing.

Molecular Quantum Solutions (MQS) provides computational tools to accelerate research & development efforts by the pharma, biotech and chemical industry. Our tools make use of super- and quantum-computers with computational models and algorithms to calculate the properties of materials and chemicals in a fast and efficient way. Users are able to screen for example new materials for batteries, green solvents, new drugs and biodegradable plastics instead of conducting costly experiments in the laboratory.

SiPhotonIC is a high-tech company that offers fast and precise fabrication for your advanced silicon photonic integrated circuits (PICs) for quantum and classical photonic applications. SiPhotonIC currently provides two different silicon-on-insulator platforms, i.e. 220nm and 250nm for customers to design their silicon chips. We support our customers in all steps of the development chain: from transfering the idea properly into a PIC design, fabrication, dicing and back-end processes. Why to chose SiPhotonIC as your prototyping partner: * Fast delivery time (typically 1~3 months) * Outstanding performances * High-precision and high-resolution fabrication * Proven expertise on the development of both quantum and classical photonic integrated circuits Our services are based on electron-beam lithography (EBL, E-Beam Writer JOEL JBX-9500FSZ) for high-precision nano-fabrication of the customer designs. World-class silicon PICs and components have been developed using our platform that were published in Science, Nature Physics, Nature Communcations, Nano Letters, Nanoscale, Scientific Reports etc. Our current technological developments include a SiN platform and Lithium Niobate/Si hybrid platform.
