Mission Statement:


Quantum Technology Laboratories GmbH (QTLabs) was founded in 2017 as a spin-off of fundamental physics research the Austrian Academy of Sciences. Our team shares the common vision of advancing quantum communications from proof-of-concept experiments to commercial applications. We provide technology development and consulting in photonic quantum information processing technologies to private and public entities. Our range of services covers the full spectrum from feasibility analyses and consulting to system designs and hardware prototyping. Our team has unique expertise in fiber- and satellite-based long-distance quantum communication. The majority of our employees are accomplished researchers from prestigious institutes, such as the Institute of Quantum Optics and Quantum Information (IQOQI) in Vienna, where they have made significant scientific contributions to advancing quantum science from laboratory experiments to real applications, in particular in space scenarios using satellites.

Our Market

As a spin-off of the Austrian Academy of Sciences, the company aims commercial exploitation of basic science results in quantum optics and quantum communications. In particular, our main focus is Quantum Key Distribution (QKD). QTLabs team accumulates both academic and basic experience in Research and Development projects, many of them involving technology transfer and industrial exploitation of scientific results. Among QTLabs current activities, the most relevant are feasibility studies and to develop mission designs not only to bring quantum communication into space, but also on international glas fiber links and data centers.

Due to the employees high visibility in the international science landscape QTLabs was one of the first quantum communication enterprises to be contacted by the European Space Agency (ESA).
