Descripción del proyecto
Hacia una red europea de satélites para la distribución cuántica de claves
La distribución cuántica de claves (DCC), o criptografía cuántica, utiliza la física cuántica para generar e intercambiar «claves» secretas que solo conocen las dos partes que las comparten. Este mecanismo permitirá la futura interoperabilidad de las redes de comunicación cuántica y ayudará a prepararse para las amenazas que expondrán los ordenadores cuánticos. La DCC requiere una red de satélites que permita compartir las claves aleatorias. El equipo del proyecto QUDICE, financiado con fondos europeos, desarrollará los componentes y subsistemas de la DCC espacial necesarios para crear una red europea de satélites que presten servicios de DCC. El equipo prevé validar y demostrar las tecnologías en un entorno pertinente, así como proporcionar una hoja de ruta hacia la consecución de un sistema real en un entorno operativo.
Objetivo
The protection of sensitive information is of crucial importance in our society: the security of money transfer, commercial transactions, medical data, remote control of critical infrastructures (power grid, telecom etc.) are key assets for EU citizens. Quantum Key Distribution (QKD) is a promising solution to protect digital communications, guaranteeing unconditional security based on the laws of quantum mechanics rather than on the computation capability of an adversary. QKD requires a satellite network to allow the sharing of random keys between two legitimate users at the European scale. The main target of QUDICE is the development of the components and subsystems for quantum communication and optical systems for space-based QKD enabling the realization of a European network of satellites with quantum key distribution as the main service. Specific objectives of the project include:
- the development of a TRL6 space-qualifiable source for discrete variable (DV) QKD
- the development of a TRL5-6 space-qualifiable Quantum Random Number Generator (QRNG)
- the development of a TRL6 space-qualifiable satellite Pointing and Tracking (PAT) system
- the development of a TRL5-6 space-qualifiable Entangled Photon Source (EPS)
- the development of a TRL5-6 space-qualifiable Continuous Variable (CV) QKD source
- the development of a TRL6 space-qualifiable onboard 5G system for QKD post-processing support and QKD-secured connectivity service
- the development of simulations and testbeds to assess quantum satellite communications components
- the definition of the roadmap towards TRL9 for the developed systems
