The protocol of reference-frame-independent measurement-device-independent quantum key distribution has many advantages compared with other existing quantum key distribution protocols, and thus has many interesting applications in the field of quantum information. In this paper, we propose a scheme on the reference-frame-independent measurement-device-independent quantum key distribution by implementing heralded single-photon sources, where we only need to modulate pump light into two intensities (vacuum and nonvacuum). Through numerical simulations, we demonstrate that our scheme can exhibit much longer transmission distance than the standard three-intensity decoy-state measurement-device-independent quantum key distribution under a reference-frame-independent scenario.
