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(biāo)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(chǔ)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(chǎn)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(biāo)定，本文介紹了該應(yīng)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(biāo)定，即不需要另一個探測器而實現(xiàn)絕對標(biāo)定。
