我们提出了一个线性光学方案，用于计算噪声信道中双光子偏振纠缠Bell态的无误差分布。该方案可以应用于基本量子中继器协议，在效率和系统复杂度方面具有潜在的显着改善。该方案基于光子的偏振和时间仓编码的使用，并且可以利用当前可用的技术执行单对单步纯化。
We present a linear optical scheme for error-free distribution of two-photon polarization-entangled Bell states over noisy channels. The scheme can be applied to an elementary quantum repeater protocol with potentially significant improvements in efficiency and system complexity. The scheme is based on the use of polarization and time-bin encoding of photons and can perform single-pair, single-step purification with currently available technology.
