Quantum R&D

Quantum Key Distribution (QKD) is a technology that exploits a fundamental principle of quantum physics – observation causes perturbation – to exchange cryptographic keys over optical fibre networks with provable security. It is attracting a growing interest in the scientific community as the need for quantum-safe encryption grows to counter the threat of a quantum computer.

The Clavis3 QKD Platform – clavis is the ancient latin word for key – was developed by ID Quantique to serve as a versatile research tool.

The Clavis3 system comprises two stations, the transmitter unit, Clavis3-A and the receiver unit, Clavis3-B. Each station consists of an optical and electronic platform, which must be controlled by an external computer, which is linked to the station through an Ethernet connector.

The Clavis3 system was designed as a research platform, with both automated and manual operations. The user can therefore experiment with different parameters and study various setups. The optical platform is well documented in scientific publications and has been extensively tested and characterized.

What’s new?

New optical scheme

The COW protocol is a simple, high bit-rate protocol that can be used for long-distance key distribution

Faster key processing

All key distillation steps are hardware-based, implemented in an FPGA inside the platform, for enhanced speed and reliability


Clavis3 comes with a comprehensive software suite including:

  • QKD Menu Application, which controls and operates the Clavis3 manually
  • QKD Sequence Application, an automated quantum key distribution and storage program
  • QKD Device Communication Protocol, which allows users to write customized programs to control and operate the devices

  • Quantum cryptography research
  • Pilot network deployment
  • Education and training
  • Demonstrations and technology evaluation
  • QKD certification
