projective measurement meaning in Chinese

射影测度

My study involves two areas in quantum key distribution protocol . first , in the field of the b92 protocol , it is first calculated and analyzed for the holevo upper bound of b92 protocol to noise and eavesdropping , the fidelity , a lower bound on the guaranteed privacy and the capacity for classical information over phase flip channels . it is computed and validated for that projective measurements increase quantum entropy
本文主要涉及两个方面:一、 b92量子密钥分配协议方面,计算分析了b92协议对噪声和窃听的holevo上界,以及通过相位翻转信道的信道保真度,信道可靠的保密性量子熵下界和对经典信息的容量,计算验证了定理投影测量增加量子熵,分析了测量前后量子状态的变化,并用计算机仿真绘制了图形,能够清楚直观地分析比较。
