Reference-frame-independent (RFI) measurement-device-independent (MDI) quantum key distribution (QKD) is immune to all detector side-channel attacks and insensitive slow drifts of reference frames; thus, it a promising candidate for the realization long-distance secure communications. However, its practical performance predominantly limited by finite-data-size effect compared with standard MDI QKD. By combining collective constraint joint-study strategy our parameter estimation processes...
Decoy-state measurement-device-independent quantum key distributions (MDI-QKD) can remove all the loopholes of detection devices and establish secure keys using weak coherent sources. To further extend distance enhance rate, Chau proposed a novel framework for decoy-state MDI-QKD that supports an arbitrary number intensities investigated its performance in detail [H. F.

In practical implementation of quantum key distributions (QKD), it requires efficient, real-time feedback control to maintain system stability when facing disturbance from either external environment or imperfect internal components. Usually, a "scanning-and-transmitting" program is adopted compensate physical parameter variations devices, which can provide accurate compensation but may cost plenty time in stopping and calibrating processes, resulting reduced efficiency transmission. Here we...
Measurement-device-independent quantum key distribution (MDI QKD) is a promising method for remote sharing that can eliminate all detector side-channel attacks. However, current security proofs often overlook the potential information leakages from legitimate users' devices. In version of Trojan-horse attack (THA), malicious eavesdropper inject bright light into sources MDI QKD system and then analyze back-reflected to obtain their setting choices, thereby compromising final security. Here,...
Among all present quantum key distribution protocols, the reference-frame-independent measurement-device-independent (RFI-MDI-QKD) is standing out due to its high security and practicability, since it can not only remove detector-side-channel attacks, but also relax requirement of reference-frame calibrations.

The measurement-device-independent quantum key distribution (MDI-QKD) can be immune to all detector side-channel attacks. Moreover, it easily implemented combining with the matured decoy-state methods under current technology. It thus seems a very promising candidate in practical implementation of communications. However, suffers from severe finite-data-size effect most existing MDI-QKD protocols, resulting relatively low rates. Recently, Jiang et al. [Phys. Rev. A 103, 012402 (2021)]...
Measurement-device-independent quantum key distribution (MDI-QKD) completely closes the security loopholes caused by imperfection of devices at detection terminal. Commonly, a symmetric MDI-QKD model is widely used in simulations and experiments. This scenario far from real network, where losses channels connecting each user are quite different.

Reference-frame-independent measurement-device-independent quantum key distribution (RFI-MDI-QKD) is immune to both detector side channel attacks and slow drifts of reference frames, thus possesses a high level security. In the traditional protocol RFI-MDI-QKD, each legitimate user, Alice or Bob, has prepare six encoding states in three orthogonal bases ($X, Y$, $Z$), which are sent untrusted third party, Charlie. Then all successful counting events utilized for parameter estimations, suffer...
