single photon detector

基本解釋

Based on former protocols, we propose a simpler way to realize the absolute self-calibration of quantum efficiency of a single photon detector.
參考已有的方案，提出了一種更簡單的方案來實現(xiàn)單光子探測器量子效率的絕對自身標定。
Firstly, based on the analysis of some implementations of BB84 protocol, we developed a scheme of quantum key distribution by using polarization encoding and only one single photon detector.
首先，在研究BB84協(xié)議各種具體實現(xiàn)方法的基礎上，提出了一種基于偏振編碼的量子密鑰分發(fā)方案，該方案僅使用一臺單光子探測器。
In the receiver, the trigger signal for single photon detector is produced based on synchronization, and the transmission channel of light signal is divided into four ones with different delay.
接收端實現(xiàn)同步，產生單光子探測器的觸發(fā)脈沖信號，同時將光脈沖進行分路延時傳輸。

單光子探測器
A new experimental set-up for the absolute self-calibration of a single photon detector, i. e. without using a second detector, is presented.
利用光量子糾纏態(tài)可實現(xiàn)單光子探測器量子效率的絕對標定，本文介紹了該應用的實驗原理，并提出一種新的實驗方案，用雙光子糾纏態(tài)對單光子探測器量子效率進行自絕對標定，即不需要另一個探測器而實現(xiàn)絕對標定。
