From academia to commercialized solutions

Our path to seamlessly integrated hardware & software

With over two decades of expertise in scientific and applied research, qtlabs stands at the forefront of quantum communication technologies. Our mission is to transcend the boundaries of academia and pioneer commercial applications by leveraging the fundamental laws of quantum physics. We deliver seamlessly integrated hardware and software solutions tailored to both terrestrial and space-based quantum communication.

Proven Track Record in Quantum Innovation

Our legacy includes milestone achievements that continue to shape the future of quantum communication:

  • Record-Breaking Free-Space Link: Successfully established a 143 km quantum communication link between La Palma and Tenerife, demonstrating long-distance optical quantum transmission.
  • European First in Space QKD: Executed the first-ever Quantum Key Distribution (QKD) downlink from an orbiting satellite in Europe a feat yet unmatched by any other team.
