# Fast and simple one-way quantum key distribution

@article{Stucki2005FastAS, title={Fast and simple one-way quantum key distribution}, author={Damien Stucki and Nicolas Brunner and Nicolas Gisin and Valerio Scarani and Hugo Zbinden}, journal={Applied Physics Letters}, year={2005}, volume={87}, pages={194108} }

We present and demonstrate a new protocol for practical quantum cryptography, tailored for an implementation with weak coherent pulses to obtain a high key generation rate. The key is obtained by a simple time-of-arrival measurement on the dataline; the presence of an eavesdropper is checked by an interferometer on an additional monitoring line. The setup is experimentally simple; moreover, it is tolerant to reduced interference visibility and to photon number splitting attacks, thus featuring…
