Abstract

We demonstrate a polarization-encoded BB84 transmitter sourced by a SiGe light source and show that such a potentially “all-silicon” QKD scheme can operate well below the QBER threshold at which secret keys can be established.

Towards an All-Silicon DV-QKD Transmitter Sourced by a Ge-on-Si Light Emitter

Florian Honz, Nemanja Vokić, Philip John Walther +2 more

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.

Simplified polarization-encoding for BB84 QKD sourced by incoherent light of a silicon emitter

Florian Honz, Nemanja Vokić, Philip John Walther +2 more

We investigate a polarization-encoded BB84-QKD transmitter that is simplified from an architectural and technological point-of-view, demonstrating 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%, underpinning the feasibility of an all-silicon QKD transmitter.

Towards an All-Silicon QKD Transmitter Sourced by a Ge-on-Si Light Emitter

We demonstrate a novel transmitter concept for quantum key distribution based on the polarization-encoded BB84 protocol, which is sourced by the incoherent light of a forward-biased Ge-on-Si PIN junction. We investigate two architectures for quantum state preparation, including independent polarization encoding through multiple modulators and a simplified approach leveraging on an interferometric polarization modulator. We experimentally prove that the Ge-on-Si light source can accommodate for quantum key generation by accomplishing raw-key rates of 2.15 kbit/s at a quantum bit error ratio of 7.71% at a symbol rate of 1 GHz. We further investigate the impact of depolarization along fiber-based transmission channels in combination with the broadband nature of the incoherent light source. Our results prove the feasibility of a fully-integrated silicon quantum key distribution transmitter, including its light source, for possible short-reach applications in zero-trust intra-datacenter environments.
