Abstract

Quantum Key Distribution (QKD) enables the secure distribution of secret keys for cryptographic purposes between two trusted parties over a quantum channel. For reaching global-scale quantum key distribution, satellite-based approaches are most promising as already demonstrated by the Chinese MICIUS mission. Here, we summarize our efforts in building a very compact QKD sender unit featuring polarization-encoded BB84 with weak coherent pulses. The unit is suitable for deployment in cube satellites such as our missions QUBE and QUBE-II which aim to demonstrate that affordable and scalable key distribution is possible in the near future.
