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…
Experimentally validated quantum-secure federated learning over a multi-user quantum network
Zhi-Ping Liu, Xiao-Yu Cao, Hao-Wen Liu +6
Federated learning enables decentralized, privacy-preserving training but remains vulnerable to privacy leakage in the quantum era. Quantum federated learning (QFL) offers a promis…
Source-independent quantum key distribution without pre-sending entanglement
Rong-Zheng Liu, Hua-Lei Yin
Quantum key distribution (QKD) theoretically offers information-theoretic security. The prevailing approach is the prepare-and-measure BB84 protocol, which implements QKD using con…
