Quantum Key Distribution (QKD) and NaQCI.fi

Introduction to Quantum Key Distribution (QKD) and NaQCI.fi

Come and learn the basics of quantum key distribution (QKD) and what role this technology will play in securing digital communications in the future.

Time: Tuesday 11 Nov 2025 9:30 
Place: On-site at CSC, Life Science Center, Espoo

The National Finnish Quantum Communications Infrastructure (NaQCI.fi) project is part of the European Union wide effort, EuroQCI, of connecting all member states through a highly secure digital communications network.

In NaQCI.fi and EuroQCI, network security is implemented using so-called quantum key distribution (QKD), a methodology based on the fundamental laws of physics, and ideally therefore, immune to decryption.

In this workshop, we go through the fundamentals of QKD-based encryption and communications, and discuss the present state of affairs. The discussion is based on practical experiences gained during the NaQCI.fi project. Participants will also have the opportunity to see the technology in action in a live demonstration.

Target audience: Persons interested in quantum-safe communications and QKD, affiliated with a Finnish organisation. No previous experience with the technology required.

Agenda

9:30–10:00 – Registration and coffee

10:00–12:00 – Introduction to Quantum Key Distribution (QKD): Fundamentals and Methods
An overview of QKD, covering the basic principles of quantum cryptography, key distribution protocols, and the theoretical foundations that ensure secure communication.

12:00–13:00 – Lunch Break
A chance to network and discuss the morning session over lunch.

13:00–15:00 – QKD Hardware and Demonstration
Focus on the practical aspects of QKD, including hardware components used in quantum communication systems. A live demonstration will showcase real-world implementation.
