General scheme for superdense coding between multiparties

TLDR
Dense coding or superdense coding in the case of high-dimension quantum states between two parties and multiparties is studied in this paper.
Abstract
Dense coding or superdense coding in the case of high-dimension quantum states between two parties and multiparties is studied in this paper. We construct explicitly the measurement basis and the forms of the single-body unitary operations corresponding to the basis chosen, and the rules for selecting the one-body unitary operations in a multiparty case.

Improving the security of multiparty quantum secret sharing against Trojan horse attack

TL;DR: This work analyzed the security of the multiparty quantum secret sharing protocol and found that this protocol is secure for any other eavesdropper except for the agent Bob who prepares the quantum signals as he can attack the quantum communication with a Trojan horse.

Quantum secure direct communication and deterministic secure quantum communication

TL;DR: This review article reviews the recent development of quantum secure direct communication (QSDC) and deterministic secure quantum communication (DSQC) which both are used to transmit secret message, including the criteria for QSDC, some interesting QS DC protocols, the DSQC protocols and QSDF network, etc.
