Quantum secret sharing protocols with high efficiency

Measuring the two photons from a Bell state will yield certain correlations between the measurement results. Based on this feature, two quantum secret sharing protocols were proposed. The security against several general attacks was analysed and it was shown that both schemes are secure in theory. F...

Description
Summary:Measuring the two photons from a Bell state will yield certain correlations between the measurement results. Based on this feature, two quantum secret sharing protocols were proposed. The security against several general attacks was analysed and it was shown that both schemes are secure in theory. Furthermore, both schemes achieve full efficiency and there is no need to utilize multi-particle entanglement, which is relatively more difficult to generate.
