Why QKD; Why QuSAT
3
QKD is Quantum‐Safe today
QKD adds a layer of security (not exclusive!)
QKD from space removes the distance limitation of QKD
Good add‐on to our new tool chest!

Quantum Key Distribution (QKD)
• Point to Point: offered since 2007 < 100km
• Trusted Nodes: Longer distances and meshed networks

QuSAT driving ideas
7
• Keep the space segment simple
• Low cost
• Low cost User Terminals
ID Quantique & ALTYN © Copyright 2017
• A Quantum Channel to exchange qubits between the satellite and ground user terminals, for a sufficient duration (3-5 min)
• A classical communication channel to extract secret keys from the qubits
• A safe key storage, management and distribution system
QuSAT Functional Requirements

• A Laser Communication Terminal (LCT), with an added
Quantum Channel Data rate: 1 Gbit/s
Diameter of the telescope: 10-15 cm
Pointing accuracy: <10 rad
• An Acquisition, Pointing & Tracking System (APT)
• A QKD Management System & a Hardware Security Module
(HSM)
• A Radio Communication Channel
QuSAT Technical Requirements

A new protocol: Quantum-Enhanced PLC
11
Assumptions:
• Eve cannot intercept the beam
without being discovered
• Eve only limited by QM
Advantages:
• Simpler systems at both ends
• More power

• T1: Lock‐in & clock synchro (<60 s)
• T2: Quantum Channel: qubits transmission (>180 s)
• T3: Keys processing & securityverification (…)
