Horizontal Free-Space-Links

Terrestrial Free-Space-Link

At qtlabs, our free-space communication systems are built on the foundational success of ground-breaking heritage experiments, including long-distance quantum transmission achievements. These systems represent the DNA of our pioneering work in quantum communications.

Long-Distance Free-Space Communication Expertise

Leveraging our experience in establishing long-distance quantum links, qtlabs has developed a portfolio of robust and adaptable free-space communication solutions, suitable for both:

• Laser optical communication
• Quantum communication applications, including QKD and entanglement-based protocols

System Architecture

Each free-space link is designed as a modular platform and typically consists of the following:

• Sender and Receiver Units: Configurable as standalone systems or integrated into broader optical ground infrastructure.
• Precision Telescopes: Offered with apertures ranging from 20 cm to 40 cm, optimized for high signal fidelity.
• High-Performance Mounting Systems: Ensure stability, precision tracking, and reliable operation under varying environmental conditions.
• Free-Space Links up to 40km distance

Advanced Features & Customization

Our platforms can be enhanced with the following advanced capabilities:

• Laser optical communication system
• Integration of Quantum Receiver Systems for secure QKD applications
• Tip/Tilt System
• Adaptive Optics

These components are designed for maximum interoperability and adaptability to diverse mission environments, including both ground-to-ground and ground-to-space quantum communication scenarios.

Tailored Solutions for Quantum Links

We collaborate closely with our partners to deliver custom-engineered solutions, fully aligned with your specific free-space link requirements, communication distance, and environmental constraints.
