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.

Quantum Machines develops the OPX+ pulse processor — a purpose-built classical processor for real-time quantum control that handles the precise pulse sequences needed to manipulate qubits. The company's Quantum Orchestration Platform provides low-latency feedback loops essential for error correction. Quantum Machines works across all qubit modalities and has partnerships with major quantum computing labs worldwide. It is part of NVIDIA's NVQLink ecosystem for GPU-QPU integration.

Qblox is a QuTech spin-out that engineers scalable control electronics for quantum computers. Its modular Cluster system provides high-fidelity microwave control and readout for superconducting, spin, and NV center qubits. Qblox supplied the control stack for the Q-PAC system (the first commercially deployable open-architecture quantum computer in the US) and was selected by DOE/Fermilab to manufacture the QICK quantum control platform. Partners include Bluefors (cryogenic integration), Q-CTRL (calibration), and QuantWare.
