2 Presentation of ID Quantique Scrambled Message Alice Bob Symmetric Cryptography Secret Key Secret Key 2007: The first commercial QKD device 2017: A world leader in ground QKD systems 2

3 Why QKD; Why QuSAT 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! 3

4 Quantum Key Distribution (QKD) Point to Point: offered since 2007 < 100km Trusted Nodes: Longer distances and meshed networks Trusted node project between Cambridge and Ipswich Cambridge Exchange Ipswich Exchange University Labs Cambridge BT Labs Adastral Park Space: The future for global QKD networks

5 QuSAT: A Swiss QKDS project A Partnership between: Funded by the Swiss Space Office (SSO) Phase 0 completed in 2016 Phase A kicked off on 1 May 2017 Phase A will last 12 months 5

6 Phase A: Two Objectives 1 - Technical To design, develop and deliver a Quantum Key Distribution Service from space via a LEO satellite Cost effective Reliable Secure 2 - Commercial To develop a commercial business, offering the next generation data encryption capabilities Strategic partnerships Customer base Private Equity 6

7 QuSAT driving ideas Low cost Keep the space segment simple Low cost User Terminals 7

8 QuSAT Functional Requirements A Quantum Channel to exchange qubits between the satellite and ground user terminals, for a sufficient duration (3-5 min) Alice A classical communication channel to extract secret keys from the qubits A safe key storage, management and distribution system 8 Bob

9 QuSAT Technical Requirements A Laser Communication Terminal (LCT), with an added Quantum Channel Data rate: 1 Gbit/s Diameter of the telescope: cm Pointing accuracy: <10 rad An Acquisition, Pointing & Tracking System (APT) A QKD Management System & a Hardware Security Module (HSM) A Radio Communication Channel 9

10 Physical Layer Crypto Wyner wiretap Assumptions: Eve cannot intercept the beam without being discovered Eve has limited technology (detector noise) 10

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

12 QuSAT Technical Requirements T1: Lock in & clock synchro (<60 s) T2: Quantum Channel: qubits transmission (>180 s) T3: Keys processing & security verification ( ) Ground User terminal 12

13 QuSat: Initial requirements Payload Optical payload Mass: < 30 kg Power consumption: < 80 W Service life: 5 year Pointing accuracy: 10 rad Protected perimeter, spherical keep-out zone, centered on the satellite, of [1000 m] TBC radius Spacecraft: Overall mass: 150 kg Power: 100 W Pointing accuracy, knowledge, stability Position knowledge Slew rate Payload accommodation options 13

14 Key figures: Loss and noise budgets Wavelength (nm) Transmitter diameter Receiver diameter (mm) Detection efficiency Transmittance Parameter Loss (db) Loss (db) Loss (db) Loss (db) Divergence Pointing error of 10 µrad Transmittance Collection & detection efficiency Total loss

15 QuSAT coverage over selected countries 15

16 QuSAT Business model Options: o Complete ownership o Single user terminal o QKD Hub Key distribution: o Yearly fee: 100 k o KaaS : 2 5 per key 16

17 An aggressive roadmap Kick-Off: On-going Phase A Demonstration & Pilot Services Identifying Customers, Partners & Investors Commercial Ops. Phase B/C/D
