Demonstrations
This task will promote the demonstration of the PTQCI. This includes the demonstration of using QKD systems to encrypt/decrypt confidential data using different network cryptographic protocols, such as the AES, and its use on cypher machines. The use of QKD in classical encryption allows for both robust security and authentication and provides compatibility with SDN.
The use of QKD in cypher machines allows for secure automatic key distribution based on a one-time pad between different cypher machines. In this task we will demonstrate the feasibility of these technologies embedded in classical (software-defined) networks.
Use Cases (1/1)
PTQCI Use Case Demonstration - November 26, 2025
On November 26, the National Security Office (Gabinete Nacional de Segurança), in Lisbon,
hosted the successful technical demonstration “Seed of the PTQCI Network,” showcasing the project’s key components and engaging several
key national institutions. During the demonstration, two practical use cases were presented:
- A secure network interconnecting four institutions in Lisbon, employing PT cipher machines to ensure encrypted video communications and other
interactive functionalities.
- A secure multiparty computation protocol supported by QKD, used to estimate the probability of satellite collisions based on confidential
inputs.
PTQCI leverages European technology while also validating the nationally developed QKD node within the DISCRETION project.
This constitutes a foundational milestone for the deployment of EuroQCI in Portugal. The event also explored the next steps
for consolidating Portugal’s first quantum communication infrastructure.
Field Trails (3/0)
- Repmus NATO Exercise 2024 - September 17, 2024
- Experimental Fild Trail: FCCN, IPTelecom and Warpcom - November 01, 2023
- Repmus NATO Exercise 2023 - September 21, 2023
Repmus NATO Exercise 2024 - September 17, 2024, Troia
Partners from PTQCI project participated on a demonstration in an operational scenario for the first time at the REPMUS
(Robotic Experimentation and Prototyping with Maritime Unmanned Systems) exercise in Troia and Sesimbra, Portugal.
Organized by the Portuguese Navy and NATO, this 14th edition brings together over 2,000 participants from 30 countries,
facilitating demonstrations and meetings. The system integrates a Software Defined Network, Continuous-Variable Quantum Key Distribution Node,
Key Management System, Cipher Machines and Software Defined Radios.
Partners: Instituto de Telecomunicações, Deimos, Instituto Superior Técnico, Altice Labs, Adyta, Telefónica, Universidad Politécnica de Madrid,
AIT Austrian Institute of Technology and Nextworks. Supported by: Gabinete Nacional de Segurança and Estado-Maior-General das Forças Armadas.
Experimental field trial: FCCN, IPTelecom, and Warpcom - November 01, 2023, Lisbon
FCCN, IPTelecom and Warpcom, partners in the Portuguese Quantum Communications Infrastructure – PTQCI project, joined forces to implement a modern secure communications link, through a system that combines a quantum cryptographic technology with network and security solutions, connecting two points, on a 14-kilometer route, in Lisbon.
A Quantum Key Distribution (QKD) system was used to perform the activity, with the purpose of guaranteeing the security of the generation of cipher keys between two points. The exercise highlights the importance of the technology for data protection and encryption and for strengthening the communication infrastructure in Portugal.

Repmus NATO Exercise 2023 - September 21, 2023, Troia
Three of our partners, Quantum Communications Group (Instituto de Telecomunicações - Aveiro), Elecnor Deimos, and Gabinete Nacional de Segurança (GNS), participated in a field demonstration of a cutting-edge quantum-link CV-QKD system developed in the laboratory to exchange confidential information between a command center and a docked navy frigate.
The REPMUS & NATO Dynamic Messenger 2023 (DYMS23) exercises were organized by the Portuguese Navy at the Operational Experimentation Center in Troia, Portugal.
