Summary: In this paper, we propose a one-sided measurement-device-independent quantum secure direct communication (1SMDI-QSDC) protocol that is independent of detection loopholes and weakens the requirement for state preparation. Realistic experimental settings are used to analyze the secrecy capacity of this protocol, and the results show that our protocols can achieve secure communication over a few hundred kilometers. Furthermore, we find that the coding technology of increasing capacity using masking (INCUM) can mitigate the degradation of the maximum distance of secure communication when the state preparation is highly untrustworthy.

Summary: In this study, a measurement-device-independent (MDI) three-party quantum secure direct communication (QSDC) protocol based on polarization-spatial-mode hyperentanglement is proposed. It can resist possible attacks and enhance the security of three-party QSDC under practical experimental conditions. In one round of communication, two parties can each send 2 bits of secure messages to the third party. Our MDI-3P-QSDC protocol has potential applications in future multipartite quantum communication field.

Summary: This paper introduces a hyperentanglement-based one-step DI-QSDC protocol, which enhances the security of QSDC by simplifying the experiment and reducing message loss. The protocol eliminates message loss and errors caused by channel noise through hyperentanglement heralded amplification and hyperentanglement purification, and significantly extends the communication distance.

Summary: In practical DSQC, detector-side-channel attacks are common, and encoding information in only one DOF of photons can lead to inefficiency. By utilizing the polarization-spatial-mode DOFs of photons, we propose the HC-MDI-DSQC protocol, which removes detector side channels and increases channel capacity. Theoretical analyses show that this method is advantageous in terms of security and efficiency compared with current DSQC protocols.

Summary: This paper defines two specific secure multiparty summations and presents corresponding measurement-device-independent quantum secure multiparty summation protocols. In these protocols, each party only performs simple single-particle operators, not complex quantum measurements. The proposed protocols achieve information-theoretical security, feasibility, and high performance.

Summary: Quantum secret sharing (QSS) is a multi-party quantum communication mode that can enhance security. However, the key generation rate of previous MDI-QSS is low. By using polarization-spatial-mode hyper-encoding technology and cross-Kerr nonlinearity, the key generation rate of MDI-QSS can be significantly increased.

Summary: In this Part II, a practical protocol is proposed for single-photon-memory measurement-device-independent quantum secure direct communication (SPMQC) and its secrecy capacity is analyzed. The proposed SPMQC protocol eliminates security loopholes caused by practical detectors and overcomes the limitation of unavailable high-performance quantum memory. Simulations considering realistic experimental parameters show the feasibility of implementing SPMQC with existing technology.

Summary: Recently, Cui et al. proposed a measurement-device-independent quantum key distribution (MDI-QKD) scheme based on high-dimensional encoding to increase the channel capacity of each individual photon. While claiming to improve the low-key generation rate drawback of past MDI-QKD schemes, this study identified a loophole during the security check of the third-party. By using only qubit pairs generated in the diagonal basis, a potential attack and partial inconsistency of key bits were discovered. Fortunately, a minor correction of the protocol fixed this issue.
