Improving the security of multiparty quantum secret sharing based on entanglement swapping against participant attack
Song Lin, Fei Gao, Fen-Zhuo Guo +2
In a recent paper [Z. J. Zhang and Z. X. Man, Phys. Rev. A 72, 022303(2005)], a multiparty quantum secret sharing protocol based on entanglement swapping was presented. However, as…
Threshold quantum cryptograph based on Grover's algorithm
Jian-Zhong Du, Su-Juan Qin, Qiao-Yan Wen +1
Grover's operator in the two-qubit case can transform a basis into its conjugated basis. A permutation operator can transform a state in the two conjugated bases into its orthogona…
Entanglement Split:Comment on ``Quantum secret sharing based on reusable Greenberger-Horne-Zeilinger states as secure carriers'' [Phys. Rev. A 67, 044302 (2003)]
Jian-Zhong Du, Su-Juan Qin, Qiao-Yan Wen +1
In a recent paper [S. Bagherinezhad and V. Karimipour, Phys. Rev. A 67, 044302 (2003)], a quantum secret sharing protocol based on reusable GHZ states was proposed. However, in thi…
Improving the security of quantum exam against cheating
Fei Gao, Qiao-Yan Wen, Fu-Chen Zhu
The security of quantum exam [Phys. Lett. A 350 (2006) 174] is analyzed and it is found that this protocol is secure for any eavesdropper except for the "students" who take part in…
