Abstract

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 improvements over the previous protocols. In this Comment, it is shown that the scheme has no properties as been discussed.

A Comment on the One Step Quantum Key Distribution Based on EPR Entanglement

Anirban Pathak, Kishore Thapliyal

Recently, in Sci. Rep. \textbf{6} (2016) 28767, Li et al., have proposed a scheme for quantum key distribution using Bell states. This comment provides a proof that the proposed scheme of Li et al., is insecure as it involves leakage of information. Further, it is also shown that all the error rates computed in the Li et al.'s paper are incorrect as the authors failed to recognize the fact that any eavesdropping effort will lead to entanglement swapping. Finally, it is established that Li et al.'s scheme can be viewed as an incrementally (but incorrectly)modified version of the existing schemes based on Goldenberg Vaidman (GV) subroutine.

Quantum key distribution based on entanglement swapping

Adán Cabello

Entanglement swapping between EPR pairs can be used to generate the same sequence of random bits in two remote places. A quantum key distribution protocol based on this idea is described. The scheme exhibits the following features: (a) It improves the rate of generated bits for transmitted qubit. (b) It allows Alice and Bob to generate a key of arbitrary length using a single quantum system (three EPR pairs), instead of a long sequence of them. (c) Detecting Eve requires the comparison of fewer bits. (d) Entanglement is an essential ingredient. The scheme assumes reliable measurements of the Bell operator.

In a recent paper [A. Cabello, Phys. Rev. A 61, 052312 (2000)], a quantum key distribution protocol based on entanglement swapping was proposed. However, in this Comment, it is shown that this protocol is insecure if Eve uses a special strategy to attack.

Quantum Key Distribution Scheme with High Efficiency

Gan Gao

Based on entanglement swapping, a quantum key distribution (QKD) scheme is proposed. In this scheme, the secret keys are formed by comparing initial Bell states and outcomes of entanglement swapping. Moreover, all initial Bell states prepared by Alice and Bob are completely arbitrary. As the classical information exchanged between two parties is very little, this QKD scheme has a high efficiency. In addition, in order to prevent eavesdropping, decoy particles are used.
