Abstract |
|
|
| The measurement device independent (MDI) Quantum Key Distribution (QKD) is a practically implementable method for
transmitting secret keys between distant partners performing quantum communication. SARG04 (Scarani-Acīın-Ribordy-Gisin 2004)
is a protocol tailored to struggle against photon number splitting (PNS) attacks by eavesdroppers. Considering its decoy implemented
MDI-QKD version, we analyse its performance from secret key bitrate versus communication distance point of view. Among several
factors such as error correction function, dark counting rate (DCR) and quantum efficiency, considered for achieving the largest
key bitrate versus longest communication distance, we infer that the most promising for MDI-QKD SARG04 protocol is the DCR
representing a challenge to optical material scientists. |
