recommendations! Published in 2020 at "International Journal of Theoretical Physics"

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: 10.1007/s10773-020-04571-5

Abstract: We propose a quantum cryptography based on an algorithm for determining a function using continuous-variable entangled states. The security of our cryptography is based on the Ekert 1991 protocol, which uses an entangled state. Eavesdropping… 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.
