阅读说明:本技术 光子输出的方法和装置 (The method and apparatus of photon output ) 是由 熊春乐 张翔 梁恒惠 于 2017-04-07 设计创作,主要内容包括:本申请提供了一种光子输出的方法和装置,可以提高单位时间内同时输出多个不可分辨单光子的效率。该方法包括:在前一个时间窗口结束后,第一次探测到宣告光子时,确定当前时间窗口的起始时刻为第一次探测到该宣告光子的时刻,该宣告光子和被宣告光子成对出现,该宣告光子用于宣告该被宣告光子的存在,该宣告光子和成对出现的该被宣告光子由同一个光子对源产生;在当前该时间窗口内,探测该起始时刻之后的宣告光子;调整当前该时间窗口内探测到的全部宣告光子对应的全部被宣告光子的传输时间,使该时间窗口内的全部被宣告光子在同一输出时刻输出。(This application provides a kind of method and apparatus of photon output, can be improved in the unit time while exporting multiple efficiency that can not differentiate single photon.This method comprises: after previous time window, when detecting declaration photon for the first time, at the time of the initial time of actual time window is determined to detect the declaration photon for the first time, the declaration photon and it is declared photon and occurs in pairs, the declaration photon for declaring that this is declared the presence of photon, the declaration photon and occur in pairs this be declared photon and generated by the same photon pair source;In the current time window, the declaration photon after the initial time is detected;The transmission time that the corresponding whole of whole declaration photons detected in the current time window is declared photon is adjusted, so that the whole in the time window is declared photon and is exported in same output time.)
