泊松光源的非泊松统计及其在被动诱饵态量子密钥分发中的应用

Non-Poissonian statistics from Poissonian light sources with application to passive decoy state quantum key distribution

Marcos Curty, Tobias Moroder, Xiongfeng Ma, Norbert Lütkenhaus

摘要:

我们提出了一种方法来制备不同的非泊松信号脉冲的泊松光子数分布的来源,只用线性光学元件和阈值光子探测器。该方法允许简单的被动制备用于量子密钥分发的诱饵态。我们表明,由此产生的关键利率是可比的泊松信号的强度的主动选择的性能。

英文摘要:

We propose a method to prepare different non-Poissonian signal pulses from sources of Poissonian photon number distribution using only linear optical elements and threshold photon detectors. This method allows a simple passive preparation of decoy states for quantum key distribution. We show that the resulting key rates are comparable to the performance of active choices of intensities of Poissonian signals.
