The performance of reference-frame-independent measurement-device-independent quantum key distribution

Reference-frame-independent measurement-device-independent quantum key distribution (RFI–MDI–QKD) is a promising approach for practical quantum communication. The detector side channel attacks could be removed without aligning the reference frames. By considering the statistical fluctuations, background counting rate and the polarization misalignment fluctuation, the performance of the RFI–MDI–QKD is analyzed under the condition of one, two and infinite decoy states. Moreover, the numerical simulation results are presented which offer significant reference for practical applications of RFI–MDI–QKD.
