Side-channel-free quantum key distribution with practical devices
Cong Jiang, Zong-Wen Yu, Xiao-Long Hu +1
Based on the idea that there is no side channel in the vacuum state, the side-channel-free quantum key distribution (SCFQKD) protocol was proposed, which is immune to all attacks i…
Universal approach to sending-or-not-sending twin field quantum key distribution
Xiao-Long Hu, Cong Jiang, Zong-Wen Yu +1
We present the method of decoy-state analysis after bit-flip error correction and using confidential observed numbers. Taking this tool we then construct a universal approach to se…
Quantum Digital Signatures with Random Pairing
Ji-Qian Qin, Cong Jiang, Yun-Long Yu +1
Digital signatures can guarantee the unforgeability and transferability of the message. Different from classical digital signatures, whose security depends on computational complex…
Composable security for practical quantum key distribution with two way classical communication
Cong Jiang, Xiao-Long Hu, Zong-wen Yu +1
We present methods to strictly calculate the finite-key effects in quantum key distribution (QKD) with error rejection through two-way classical communication (TWCC) for the sendin…
Twin-Field Quantum Key Distribution over 511 km Optical Fiber Linking two Distant Metropolitans
Jiu-Peng Chen, Chi Zhang, Yang Liu +16
The basic principle of quantum mechanics guarantee the unconditional security of quantum key distribution (QKD) at the cost of inability of amplification of quantum state. As a res…
Field Test of Twin-Field Quantum Key Distribution through Sending-or-Not-Sending over 428 km
Hui Liu, Cong Jiang, Hao-Tao Zhu +18
Quantum key distribution endows people with information-theoretical security in communications. Twin-field quantum key distribution (TF-QKD) has attracted considerable attention be…
