BMW Group (Quantum Computing)

planqc is a Munich-based spin-out from the Max Planck Institute of Quantum Optics, developing a unique approach to neutral-atom quantum computing by trapping individual atoms in optical lattices. This allows for extremely high qubit densities and scalability. The company is part of the Munich Quantum Valley ecosystem and received significant DLR (German Aerospace Center) funding. planqc represents Germany's most prominent quantum computing hardware startup.

eleQtron is a Siegen-based trapped-ion quantum computing company developing the MAGIC (MAgnetic Gradient Induced Coupling) technology, which uses individually addressed microwave fields instead of lasers to control ions. This approach promises significantly easier scaling since microwave electronics are more mature and cheaper than laser systems. eleQtron has received DLR funding and is part of Germany's growing quantum hardware ecosystem.

Swabian Instruments develops high-performance time-tagging and pulse counting instruments used in quantum optics, quantum computing, and quantum communication experiments. Their Time Tagger product line provides picosecond-resolution timing measurements essential for photonic quantum computing and single-photon detection. Based in Stuttgart, the company serves quantum research labs globally.

Toptica is a Munich-based precision laser manufacturer whose products are essential for trapped-ion and neutral-atom quantum computing. Trapped ions need specific laser wavelengths for trapping, cooling, and state manipulation, while neutral-atom systems require lasers for optical tweezers and atomic excitation. Toptica serves as a critical supply chain component for companies like IonQ, Quantinuum, Pasqal, QuEra, and virtually every academic ion/atom quantum lab.
