ARQUE Systems
ARQUE Systems develops silicon electron-spin quantum computers from research at RWTH Aachen and Forschungszentrum Jülich. Its scaling strategy combines semiconductor fabrication, electron transport between operating locations and eventual integration with cryogenic control electronics. The intended value is a compact processor architecture that can connect qubits without dedicating a separate control path to every interaction. Based in Aachen, Germany.

What remains unresolved
The company’s large qubit-count roadmap and comparative performance multipliers are ambitions, not verified capacities of the announced small processor.
The next question to watch
Demonstrate larger shuttling-connected registers with measured operation errors.
A research question, not a promised milestone.QubitWire coverage
