Fake one-time pad cannot be used to improve the efficiency of quantum communication
Fei Gao, Su-Juan Qin, Qiao-Yan Wen +1
Two misuses of one-time pad in improving the efficiency of quantum communication are pointed out. One happens when using some message bits to encrypt others, the other exists becau…
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…
