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…
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…
General theory of quantum fingerprinting network
Ji-Qian Qin, Jing-Tao Wang, Yun-Long Yu +1
The purpose of fingerprinting is to compare long messages with low communication complexity. Compared with its classical version, the quantum fingerprinting can realize exponential…
Quantum enhanced optical phase estimation with a squeezed thermal state
Juan Yu, Yue Qin, Jinliang Qin +4
Quantum phase estimation protocols can provide a measuring method of phase shift with precision superior to standard quantum limit (SQL) due to the application of a nonclassical st…
Guessing probability in quantum key distribution
Xiang-Bin Wang, Jing-Tao Wang, Ji-Qian Qin +2
On the basis of the existing trace distance result, we present a simple and efficient method to tighten the upper bound of the guessing probability. The guessing probability of the…
