系列超导纳米线单光子探测器的最佳幅度复用

Fabio Chiarello, Roberto Leoni, Francesco Martini, Francesco Mattioli, Alessandro Gaggero

摘要:

超导纳米线单光子探测器(SNSPD)的集成阵列已经显示出诸如光子数分辨率、单光子成像和符合检测的能力,并且还可以有效地用于与量子光学相关的其他不同应用中。这种应用的日益复杂性需要使用多路复用方案来同时读出不同的检测器。一个简单的多路复用方案可以实现通过安排一系列SNSPD元件,分流适当的电阻。这项工作的目标是调查和优化这一计划,开发一个通用的方法,能够确定任何不同的应用程序的分流电阻的最佳设置。所得到的方法是非常普遍的,并可以扩展到其他检测系统。

英文摘要:

Integrated arrays of Superconducting Nanowire Single Photon Detectors (SNSPDs) have shown capabilities such as Photon Number Resolution, single photon imaging and coincidences detection, and can be effectively used also in other different applications related to quantum optics. The growing complexity of such applications requires the use of multiplexing schemes for the simultaneous readout of different detectors. A simple multiplexing scheme can be realized by arranging a series of SNSPDs elements, shunted by appropriate resistances. The goal of this work is to investigate and optimize this scheme, developing a general method able to identify the optimal sets of shunting resistences for any different application. The methodology obtained is very general, and can be extended to other detection systems.
