对“量子通信的确定性六态协议”的评论[Phys. Lett. A 358(2006)85]

Comment on "Deterministic six states protocol for quantum communication" [Phys. Lett. A 358 (2006) 85]

摘要:

在[J.S. Shaari,M. Lucamarini,M.R.B. Wahiddin,Phys. Lett. A 358(2006)85-90]已经开发了用于量子通信的确定性六态协议(6DP)。该协议是基于三个相互无偏基地和四个编码算子。信息通过来自不同基地的两个量子比特在用户之间传输。研究了三种攻击:拦截重发攻击(IRA),双重CNOT攻击(2 hocTA)和量子中间人攻击。在这封信中,我们表明IRA和2 hocTA没有得到适当的解决。例如,我们发现,在IRA的控制模式下检测到夏娃的概率是70%,而不是以前的研究中的50%。此外,在2 hocTA中,Eve只能获得50%的数据,而不是前面所说的全部数据。

英文摘要:

In [J.S. Shaari, M. Lucamarini, M.R.B. Wahiddin, Phys. Lett. A 358 (2006) 85-90] the deterministic six states protocol (6DP) for quantum communication has been developed. This protocol is based on three mutually unbiased bases and four encoding operators. Information is transmitted between the users via two qubits from different bases. Three attacks have been studied; namely intercept-resend attack (IRA), double-CNOT attack (2CNOTA) and quantum man-in-the-middle attack. In this Letter, we show that the IRA and 2CNOTA are not properly addressed. For instance, we show that the probability of detecting Eve in the control mode of the IRA is 70% instead of 50% in the previous study. Moreover, in the 2CNOTA, Eve can only obtain 50% of the data not all of it as argued earlier.
