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: 10.1016/j.ifacol.2019.09.139
Abstract: Abstract Reconstructing high-dimensional quantum state accurately with noise is a challenging problem, because of the probabilistic measurements of quantum states and the exponential growth of the computation in terms of the number of qubits. In… read more here.
