DOI: 10.1007/s10773-020-04427-y
Abstract: Quantum secret sharing (QSS) is a project to distribute a secret message to multi-parties, who cannot restore it individually only need to cooperate in order to decode it. Here we design a five-partite QSS scheme… read more here.

DOI: 10.1063/5.0004411
Abstract: In principle, the number of orbital angular momentum (OAM) eigenstates is unbounded; therefore, OAM multiplexing could greatly increase the transmission rate. Compared with optical fibers, free-space channels fluctuate randomly over time due to the effects… read more here.
