With the rise of quantum computers, quantum communication and quantum internet become very relevant. 
Satellites can be used to send quantum information over long distances, which is not possible with optical fibres due to signal loss. 
Moreover, they can be used to entangle distant quantum computers on the ground to create a web of connected(entangled) 
quantum nodes. 
Space-based Quantum Key Distribution (QKD) is a first step towards this worldwide quantum communication network. 
Based on fundamental quantum mechanical principles, an encryption key is shared via free space between two distance receivers without an eavesdropper being able to intercept it without us knowing it. 

Bob Dirks will immerse you in the fascinating field of quantum technology and its use in space. I will explain the basic principles behind quantum communication and QKD in particular, and TNO’s activities related to it. The lecture aims for TU students and non-expert staff as well.
