A payload for satellite quantum communication on a CubeSat — •Ömer Bayraktar1,2, Jonas Pudelko1,2, Imran Khan1,2, Gerd Leuchs1,2, and Christoph Marquardt1,2 — 1Max Planck Institute for the Science of Light, Erlangen, Germany — 2Institute of Optics, Information and Photonics, Friedrich-Alexander University Erlangen-Nürnberg
The limited range of quantum key distribution (QKD) in fiber based systems lead to several projects aiming for the development of a satellite based QKD infrastructure. For smaller satellite missions with a stringent demand on size, weight and power photonic integrated circuits (PICs) are a convenient way to implement all necessary optical functions.
In this work, we present a CubeSat payload for the demonstration of quantum communication technology in space. It contains an integrated sender for modulated weak coherent states, as well as an integrated quantum random number generator (QRNG) based on measurements of the quantum optical vacuum state. In practice, both systems are implemented on Indium-Phosphide PICs and contained on a 10x10cm PCB.
These developments will be tested as a part of the CubeSat mission QUBE.
