The system has naturally self-alignment and compensation of\nbirefringence and also has enough efficiency against polarisation dependence.\nMoreover it is easily applicable to multi-party. Key creation with 0.1 photon\nper pulse at a rate of 1.2KHz with a 5.4% QBER over a 200m fiber was realized.",
