ASA600 onDDM200 for ODK

Quantum Key Distribution with ASA600 on DDM200

In July 2025, an ASA600 telescope equipped with the DDM200 direct drive mount was delivered to Madrid for use in cutting-edge Quantum Key Distribution (QKD) research.
QKD enables the exchange of cryptographic keys using the principles of quantum physics, providing the foundation for ultra-secure global communication. The high precision and stability of ASA’s telescope and mount technology make it ideally suited for such pioneering applications.
