【摘要】：利用邏輯Bell態(tài)提出兩個(gè)分別抵抗集體退相位噪聲和集體旋轉(zhuǎn)噪聲的可控的魯棒量子對(duì)話(huà)協(xié)議。協(xié)議的量子資源是利用DF(Decoherence free)態(tài)構(gòu)造的邏輯Bell態(tài),在第3方的控制下,通信雙方僅需單光子測(cè)量,可獲得秘密消息,控制方卻不能獲得任何秘密消息。所提出協(xié)議最大優(yōu)點(diǎn)是第3方可控,無(wú)信息泄露問(wèn)題�？刂品叫柽M(jìn)行Bell基測(cè)量,但通信方僅需單光子測(cè)量,通信雙方的編譯碼僅用異或操作完成,簡(jiǎn)單易行。對(duì)協(xié)議進(jìn)行安全性分析證明了協(xié)議的有效性。
[Abstract]:Using logical Bell state, two controllable robust quantum dialogue protocols are proposed to resist collective dephase noise and collective rotation noise, respectively. The quantum resource of the protocol is a logical Bell state constructed from a DF(Decoherence free) state, under the control of the third party. The two sides of the communication only need single photon measurement to obtain secret message, but the control party can not obtain any secret message. The biggest advantage of the proposed protocol is that the third party is controllable and there is no problem of information leakage. The control party needs to carry out the Bell base measurement. However, the communication party only needs single photon measurement, and the encoding and decoding of both sides of the communication is completed by XOR operation, which is simple and easy. The security analysis of the protocol proves the validity of the protocol.
