Benefits of using heralded single photon source for fiber-based Quantum Key Distribution BB84
Amor Gueddana, Moez Attia, Rihab Chatta · 2013
This paper addresses the study of the Quantum Key Distribution (QKD) BB84 protocol used at the telecoms wavelength 1550 nm with Single Mode Fiber (SMF) and realistic physical parameters features. We simulate the protocol with considering an optimized attack strategy and show that the Heralded Single Photon Source (HSPS) is more advantageous than the Attenuated Laser (AL) for mainly security considerations.
