The finite key effect of side-channel-secure quantum key distribution beyond post-selection technique
Cong Jiang, Zong-Wen Yu, Xiang-Bin Wang
By applying the framework of entropic uncertainty relation (EUR) and the Quantum Leftover Hash Lemma (QLHL), we introduce a security-proof method for variable-length side-channel-s…
The practical issues of side-channel-secure quantum key distribution
Cong Jiang, Xiao-Long Hu, Zong-Wen Yu +2
Quantum Key Distribution (QKD) leverages the principles of quantum mechanics to provide theoretically unconditional security for cryptographic key sharing. However, practical imple…
Efficient Quantum Digital Signatures over Long Distances with Likely Bit Strings
Ji-Qian Qin, Zong-Wen Yu, Xiang-Bin Wang
Quantum digital signatures (QDSs) can provide information-theoretic security of messages against forgery and repudiation. Compared with previous QDS protocols that focus on signing…
Side-channel-secure quantum key distribution
Cong Jiang, Xiao-Long Hu, Zong-Wen Yu +1
We present a result of side-channel-secure (SCS) quantum key distribution (QKD) under fully realistic conditions. Our result is not only measurement-device independent but also eff…
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…
