在50 km和100 km商用通信光纤中实现了一个鲁棒的基于相位编码的双向量子密钥分配系统。该系统可以自动补偿双折射效应，并保持稳定超过23小时。获得了低的量子误码率和高的可见性。此外，存储光纤是不必要的，并且在100 km光纤的测试中仅需要脉冲串。
A robust two-way quantum key distribution system based on phase encoding is demonstrated in 50 km and 100 km commercial communication fiber. The system can automatically compensate for birefringence effects and remain stable over 23 h. A low quantum bit error rate and high visibility are obtained. Furthermore, the storage fiber is unnecessary and train of pulses is only needed in the test with 100 km fiber.
