论文摘要
我们提出了一个接近最高的接收器，以歧视采用光子数分辨率检测器的二元相偏键相干状态。接收器利用基于所谓同源性和直接检测的歧视策略，从而导致混合方案。我们分析了在现实条件下提出的方案的性能和鲁棒性，即在存在效率低下的检测和黑暗计数的情况下。我们表明，目前的混合动力设置几乎是最省长的，并且击败了标准量子限制和肯尼迪接收器的性能。
We propose a near-optimum receiver for the discrimination of binary phase-shift-keyed coherent states employing photon-number-resolving detectors. The receiver exploits a discrimination strategy based on both the so-called homodyne-like and the direct detection, thus resulting in a hybrid scheme. We analyse the performance and the robustness of the proposed scheme under realistic conditions, namely, in the presence of inefficient detection and dark counts. We show that the present hybrid setup is near-optimum and beats both the standard-quantum-limit and the performance of the Kennedy receiver.
