Uses a silicon-based polarization encoding scheme
Shows potential for integrated quantum communication systems
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.
