The measurement-device-independent quantum key distribution (MDI QKD) was proposed to make
BB84 completely free from any side-channel in detectors. Like in prepare & measure QKD, the use of other pro-
tocols in MDI setting would be advantageous in some practical situations. In this paper, we consider SARG04
protocol in MDI setting. The prepare & measure SARG04 is proven to be able to generate a key up to two-photon
emission events. In MDI setting we show that the key generation is possible from the event with single or two-pho-
ton emission by a party and single-photon emission by the other party, but the two-photon emission event by both
parties cannot contribute to the key generation. On the contrary to prepare & measure SARG04 protocol where
the experimental setup is exactly the same as BB84, the measurement setup for SARG04 in MDI setting cannot
be the same as that for BB84 since the measurement setup for BB84 in MDI setting induces too many bit errors.
To overcome this problem, we propose two alternative experimental setups, and we simulate the resulting key rate.
Our study highlights the requirements that MDI QKD poses on us regarding with the implementation of a variety
of QKD protocols. |
