我们提出了一个易于实现的加密和测量协议,用于光子偏振的鲁棒量子密钥分配。该协议是容错的集体随机酉信道噪声。该协议不需要任何集体量子测量或量子存储器。给出了一个安全性证明和一个具体的利用自发参量下转换的线性光学实现。
We propose an easy implementable prepare-and-measure protocol for robust quantum key distribution with photon polarization. The protocol is fault tolerant against collective random unitary channel noise. The protocol does not need any collective quantum measurement or quantum memory. A security proof and a specific linear optical realization using spontaneous parametric down conversion are given.
