Abstract

We investigate the behavior of a Ge-on-Si light source and demonstrate its feasibility for polarization-encoded discrete-variable quantum key distribution following the BB84 protocol, enabling a potential 'all-silicon' QKD scheme which can operate well below the necessary QBER limit and successfully generate secret keys.
