• Abstract summary: We investigate a polarization-encoded BB84-QKD transmitter that is simplified from an architectural and technological point-of-view. We demonstrate a silicon emitter sourcing a low-complexity polarization modulator for secure-key generation at a raw-key rate of 2.8kb/s and QBER of 10.47%.
