Scalable and Highly Fault-Tolerant Circular Quantum Byzantine Agreement
Chen-Xun Weng, Ming-Yang Li, Shi-Gen Li +4
Quantum Byzantine agreement (QBA), a cornerstone of quantum blockchain, offers inherent advantages in security and fault tolerance over classical protocols, guaranteed by the laws…
Experimental Coherent One-Way Quantum Key Distribution with Simplicity and Practical Security
Xiao-Yu Cao, Xiao-Ran Sun, Ming-Yang Li +3
Coherent one-way quantum key distribution (COW-QKD) has been widely investigated, and even been deployed in real-world quantum network. However, the proposal of the zero-error atta…
Weakly-Driven Quantum Walks for Memory-Constrained Pauli Channel Learning
Yuan-Zhuo Wang, Yi-Ran Xiao, Ming-Yang Li +2
Accurate characterization of quantum noise, exemplified by the Pauli channel, is a cornerstone for building fault-tolerant quantum computers. A recent protocol (PRX Quantum 6, 0203…
Information-theoretically secure quantum timestamping with one-time universal hashing
Ming-Yang Li, Chen-Xun Weng, Wen-Bo Liu +2
Accurate and tamper-resistant timestamps are essential for applications demanding verifiable chronological ordering, such as legal documentation and digital intellectual property p…
