A Comment on the One Step Quantum Key Distribution Based on EPR Entanglement
arXiv:1609.07473
Abstract
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.
