SONG Yun. Quantum Secret Sharing Based on GHZ States Local Measurements[J]. Acta Electronica Sinica, 2019, 47(7): 1443-1448. DOI: 10.3969/j.issn.0372-2112.2019.07.007.
This paper proposes a novel quantum secret sharing(QSS)scheme based on quantum correlations among three particles in a GHZ state. Without any unitary operation or entanglement swapping
receivers can obtain the joint key by using local measurements of photons. Except a few particles which is used to check the security of quantum channel
every GHZ state can be used to share 1 bit of information. The total efficiency of the scheme approaches 100%. Taking all possible attacks into account
the security proofs are detailed. We finally establish a mathematical model about the efficiency and security of the scheme and perform simulation analyses with different parameters using MATLAB.
