在最近的一篇论文(Khokhlov,2016)中,提出了一种使用弱测量来攻击BB84的协议。这意味着通常使用的四种基本状态可以完全区分,因此拦截器可以获得携带的所有信息。我们表明,当使用标准量子力学考虑时,这种攻击失败了,正如预期的那样-即使使用弱测量,这种“单次”量子态区分也是不可能的。
In a recent paper (Khokhlov, 2016), a protocol was proposed for using weak measurement to attack BB84. This claimed the four basis states typically used could be perfectly discriminated, and so an interceptor could obtain all information carried. We show this attack fails when considered using standard quantum mechanics, as expected — such “single-shot” quantum state discrimination is impossible, even using weak measurement.
