Polar coding is the most recent encoding scheme in the quest for error correction codes that approaches the Shannon
limit, has a simple structure, and admits fast decoders. As such, it is an interesting candidate for the quantum key
distribution (QKD) protocol that normally operates at high bit error rates and requires codes that operate near the
Shannon limit. This paper describes approaches that integrate Polar codes into the QKD environment and provides
performance results of Polar code designs within the QKD protocol.
