On the information-splitting essence of two types of quantum key distribution protocols
Fei Gao, Fenzhuo Guo, Qiaoyan Wen +1
With the help of a simple quantum key distribution (QKD) scheme, we discuss the relation between BB84-type protocols and two-step-type ones. It is shown that they have the same ess…
Quantum key distribution without alternative measurements and rotations
Fei Gao, Fenzhuo Guo, Qiaoyan Wen +1
A quantum key distribution protocol based on entanglement swapping is proposed. Through choosing particles by twos from the sequence and performing Bell measurements, two communica…
Comment on "A Random Quantum Key Distribution Achieved by Using Bell States"
Sujuan Qin, Qiaoyan Wen, Fuchen Zhu
In a recent paper [J. Opt. B: Quantum Semiclass. Opt. 5 (2003) 155-157], a quantum key distribution scheme based on entanglement swapping was proposed, which exhibited two improvem…
Comment on "Quantum key distribution via quantum encryption"
Fei Gao, Sujuan Qin, Qiaoyan Wen +1
In the paper [Zhang, Li and Guo, Phys. Rev. A 64, 024302 (2001)], a quantum key distribution protocol based on quantum encryption was proposed, in which the quantum key can be reus…
Comment on "Quantum key distribution for d-level systems with generalized Bell states" [Phys. Rev. A 65, 052331 (2002)]
Fei Gao, Fenzhuo Guo, Qiaoyan Wen +1
In the paper [Phys. Rev. A 65, 052331(2002)], an entanglement-based quantum key distribution protocol for d-level systems was proposed. However, in this Comment, it is shown that t…
Comment on "Quantum secret sharing based on reusable Greenberger-Horne-Zeilinger states as secure carriers" [Phys. Rev. A 67, 044302 (2003)]
Fei Gao, Fenzhuo Guo, Qiaoyan 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…
