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.

Response to the Comment on "Paradox of Photons Disconnected Trajectories Being Located by Means of "Weak Measurements" in the Nested Mach-Zehnder Interferometer" (JETP Letters 105, 152 (2017))
在[JETP Lett. 105(3),152(2017)],对实验的矛盾结果进行了清晰而全面的分析[Phys. Rev. Lett. 111,240402(2013)]是在光的经典波动理论的基础上进行的,该理论假定了可能的光路的连续性。结果表明,实验的矛盾结果是由于不连续的光的轨迹,声称在[物理评论Lett。111,240402(2013)],而是涉及检测光子路径的所使用的方式。在[JETP Lett. 105(3),152(2017)]允许我们消除光轨迹的看似不连续性。在对该条款的评论[arXiv:1705.02137(2017)]中,此类修改被宣布为不合理。对评论的这一答复表明,这一说法没有建立在明确和合乎逻辑的论点基础上。相反,它只是断言,所提出的修改“违反了光子的痕迹的忠实性指示”。因此,评论的批评不能被认为是有根据的。因此,[JETP Lett. 105(3),152(2017)],一个新的概念,不连续的轨迹提出的作者的工作[物理。111,240402(2013)]是不必要的,仍然有效。

Why the "classical" explanation of weak values by Ferrie and Combes does not work: a comment on Phys. Rev. Lett. 113, 120404 (2014)
In Phys. Rev. Lett. 113,120404(2014)[arXiv:1403.2362],Ferrie和Combes声称,弱值可能是由干扰和对输出施加的后选择条件之间的相关性引起的统计伪影。在这篇评论中,我们表明,由弱测量引起的干扰是足够低的,明确排除了Ferrie和Combes提出的模型。
The claim that Kuwahara et al. [1] have reported the observation of a Hanbury Brown-Twiss electron antibunching dip (their Fig. 3) could possibly be explained as an electron source emission rate dependency on the light polarization. Strain on their GaAs/GaAsP sample is uniaxial, and one would expect a linear dichroism in the photoemission possibly as large as 15% [7] - much larger than the 0.1% reported effect. The same concern exist for circular polarized light.

Popp和Yan [F. A. Popp,Y. Yan,Phys. Lett. A293(2002)93]提出了一种基于单时相干态的延迟发光模型。我们表明,他们的模型的一般解决方案对应于发光,是一个线性函数的时间。因此,他们的模型与任何测量的延迟发光都不兼容。此外,他们用来描述延迟发光的振荡行为的函数不是要求解的耦合方程的解。
