Implementation of continuous variable quantum cryptography in optical fibres using a go-&-return configuration (pp326-335) Matthieu Legr, Hugo Zbinden, and Nicolas Gisin doi: https://doi.org/10.26421/QIC6.4-5-2 Abstracts: We demonstrate an implementation of quantum key distribution with continuous variables based on a go-&-return configuration over distances up to 14km. This configuration leads to self-compensation of polarisation and phase fluctuations. We observe a high degree of stability of our set-up over many hours. Key words: quantum cryptography
