About the project

The main goals

QUDICE is aimed at the creation and development of components and subsystems for space-based QKD satellite communication network. The project also seeks to create the testbeds to evaluate the components of quantum satellite communications technology as well as the tools required to simulate and monitor space quantum information networks.

The long-term goal of QUDICE is to assist in the creation of a European satellite network with QKD serving as the primary service.

The Specific Objectives

Every partner has also contributed to the QUANGO project, which was launched in January 2021. The primary goal of QUANGO is the creation of a network of 12 Unit-CubeSat LEO satellites to provide integrated capabilities for communication protected by QKD and for a 5G connection as well as the development of payloads, sub-systems, and ground stations at the breadboard level (TRL4).

QUDICE aims at increasing the TRL of essential devices for the realization of quantum communication satellites devised at QUANGO.

A visual concept

How are quantum communications integrated into space? This video gives you a brief overview of how QKD systems can be integrated into payloads in low earth orbit (LEO) and serves as links for secure communications worldwide


QUDICE will work on 2 different approaches to integrate the technology into space based satellites in Low Earth Orbits.

Sequential Rendevous

Entangled Photon Source Rendevous


The achievements of QUDICE will be possible due to a synergy of different expertise, provided by academic groups and industrial partners. The work plan will be divided into 6 Work Packages (WP) for the proper execution of the project and the achievement of the goals in a timely manner.

Design & Simulation

WP1 Design & Simulation will address the simulations and design of the various subsystems.

Subsystem manufacturing

WP2 Subsystem manufacturing will address the realization of the different subsystems


WP3 Testing will address the creation and execution of the tests necessary to reach TRL5–6 for the various subsystems


WP4 Exploitation will focus on the exploitation of the findings, including the development of IOV mission designs and roadmaps for integrating the payload onto satellites.


WP5 Dissemination is committed to spreading and communicating the project’s findings to the largest possible audience, including academic institutions, businesses, clients, and the general public, in order to generate interest in space quantum communications.


WP6 Management will address the managing of the whole project, the reporting, the financial aspects, and the communication flow between the partners and with the EU.
