Experimental demonstration of scalable quantum blockchain with exponentially superior quantum communication complexity
Feng Xie, Ming-Yang Li, Yongqiang Du +11
The paper reports an experimental implementation of a scalable quantum blockchain using weak coherent states and a circular quantum Byzantine agreement, achieving a large reduction…
A fault-tolerant quantum blockchain deployed on commercial telecommunications network
Yongqiang Du, Chen-Xun Weng, Feng Xie +10
The paper presents a hybrid quantum blockchain built on photonic integrated circuits and deployed over existing telecom infrastructure, achieving near‑half fault tolerance and abou…
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 asymmetric relativistic zero-knowledge proofs with unconditional security
Chen-Xun Weng, Ming-Yang Li, Nai-Rui Xu +6
Zero-knowledge proofs (ZKPs) are widely applied in digital economies, such as cryptocurrencies and smart contracts, for establishing trust and privacy between untrusted parties. Cl…
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…
