Compact optical sources for quantum communications

Published: 26 October 2011 Publication History

Abstract

We have developed optical sources for high bit rate Quantum Communications (QC) using active elements as well as passive schemes. These sources allow achieving 100 Mbps free space Quantum Key Distribution (QKD) with improved security and use components space qualifiable, the latter being an essential aspect for their deployment in space missions.
