Infoshare: Quantum Key Distribution (QKD) Simulation – 13 October 2021

GÉANT infoshare - Quantum Key Distribution Simulation

13 October 2021, 14:00-16:15 CEST

Quantum Key Distribution is a technology at an early stage. A QKD link requires optical connection between the network nodes. For now, there are not many quantum hardware suppliers and the hardware available is very expensive. Network simulation appears a good solution to validate the different elements that made up a QKD service (network algorithm or protocol), to save a lot of money and time in creating a testbed and to start becoming familiar with this technology. The simulators are different levels of simulation (optical layer, the key distribution service, ..). This infoshare proposes an introduction to two simulators:

  • QuISP (Quantum Internet Simulation Package) – An open-source quantum network simulation package optimised for repeater/router software development focussing on optical layer.
  • QKDNETSIM (Quantum Key Distribution Network Simulation Module for NS-3) is targeting more the Quantum key distribution service by itself.

This infoshare aims to identify if a virtual QKD testbed could be of interest for European NRENs and they could use it.


A second infoshare on Quantum Key Distribution will follow on 15 October, focusing on  QKD Physical implementation and testbed.

Practical information:

  • The Infoshare will be recorded and made available through the GÉANT GLAD Website:
  • The link and the password to join the ZOOM room will be shared with the registered attendees before the event
