Abstract

We report on a quantum key distribution (QKD) experiment where a client with an on-chip polarisation rotator can access a server through a telecom-fibre link. Large resources such as photon source and detectors are situated at server-side. We employ a reference frame independent QKD protocol for polarisation qubits and show that it overcomes detrimental effects of drifting fibre birefringence in a polarisation maintaining fibre.
