标题： "Quantum" key distribution using weak classical light waves

摘要： 通过经典宏观设备检测非常弱的经典电磁（光）波的讨论。 显示这种检测的结果可以解释为辐射量子性质的表现，尽管实际上它们与弱经典电磁波与离散原子的相互作用特性有关。 我们表明，“量子”密钥分发协议可以使用非常弱的经典光波和雪崩探测器实现，并且它具备基于纠缠光子的量子密码协议E91的所有特性。 显示英文摘要

摘要： The detection of very weak classical electromagnetic (light) waves by classical macroscopic device is discussed. It is shown that the results of such detection can be interpreted as a manifestation of the quantum properties of radiation, although in reality they are related to the peculiarities of the interaction of weak classical electromagnetic waves with discrete atoms. We show that the "quantum" key distribution protocol can be realized using very weak classical light waves and avalanche detectors, and it possesses all the properties of the quantum cryptographic protocol E91 which based on entangled photons.
