Quantum Industries

Quantum Industries is a Vienna, Austria-based quantum secure communications company developing entanglement-based quantum key distribution (QKD) technology capable of operating over 350km fiber links — significantly exceeding the practical range of conventional prepare-and-measure QKD systems.

Vienna is an exceptionally fitting location for this company: the University of Vienna and the Austrian Academy of Sciences' Institute for Quantum Optics and Quantum Information (IQOQI) host some of the world's most cited quantum entanglement researchers, including Anton Zeilinger (Nobel Prize in Physics 2022 for foundational entanglement experiments), providing a rich scientific talent pool.

The company raised $10M in seed funding and has positioned itself as a key supplier for EuroQCI — the European Quantum Communication Infrastructure initiative, an EU-funded program to build a continent-spanning quantum-secure communications network connecting European capitals, government institutions, and critical infrastructure by the late 2020s. Quantum Industries' 350km range capability is critical for EuroQCI because it must connect cities like Vienna-Prague (~280km) or Berlin-Warsaw (~520km) without requiring relay nodes at every intermediate city — extending fiber QKD range is one of the network's core technical challenges.

Satellite-based QKD (complementing fiber) can cover longer intercontinental distances, and Quantum Industries' technology contributes to the hybrid satellite-fiber quantum internet envisioned for European strategic communications independence.
