Quantum Receiver

Quantum Signal Receivers

Polarization- & phase-encoding receivers. If in doubt, choose both in one device.

At qtlabs, we specialize in delivering customized, mission-ready hardware solutions for quantum communication—tailored to meet the unique requirements of both terrestrial and space-based applications. Our Quantum Receivers are engineered to support advanced quantum communication protocols, offering flexibility across a wide range of use cases. Receivers can be seamlessly integrated with existing optical setups through single-mode fiber coupling, allowing connection to:

Free-space optical paths using Cassegrain, Nasmyth, or Coudé configurations Adaptive optics systems

Versatile Quantum Receivers

• Encoding Compatibility: Available in configurations for polarization encoding and phase encoding.
• Modular Integration: Receivers can be seamlessly integrated with existing optical setups through free-space or single-mode fiber coupling, with connections to:
  • Free-space optical paths using Cassegrain, Nasmyth, or Coudé configurations

Encoding Types

For maximum usability, we provide tailored solutions for different encoding types. Our products range includes specific encoding moduls as well as protocol-agnostic solutions with maximum flexibility in the wavelenght ranges ~800 nm to ~1550 nm

• Phase Encoding Receivers
• Polarization Encoding Receivers
• Multi-Purpose Encoding Receivers, covering both types in one device

Integrated Turn-Key Solutions

qtlabs offers fully integrated, turnkey systems that combine all critical subsystems necessary for operational readiness:

• Optical Ground Station (OGS)
• Classical Communication (Classic Com) modules
• Adaptive Optics (AO)
• Quantum Receiver

These end-to-end systems are ideal for institutions and commercial partners seeking a ready-to-deploy quantum communication infrastructure with minimal integration effort.
