Certifying optimal device-independent quantum randomness in quantum networks
Shuai Zhao, Rong Wang, Qi Zhao
Bell nonlocality provides a device-independent (DI) way to certify quantum randomness, based on which true random numbers can be extracted from the observed correlations without de…
Experimental Phase-Matching Quantum Cryptographic Conferencing in Symmetric and Asymmetric Fiber Channels
Mi Zou, Bin-Chen Li, Shuai Zhao +5
Quantum cryptographic conferencing (QCC) allows multiple parties to establish common secure keys in quantum networks with information-theoretic security. However, the secure transm…
Experimental demonstration of scalable quantum cryptographic conferencing
Haotao Zhu, Zhenhua Li, Shuai Zhao +6
Quantum network enables a variety of quantum information processing tasks, where multi-user quantum communication is one of the important objectives. Quantum cryptographic conferen…
An Improved ChaCha Algorithm Based on Quantum Random Number
Chao Liu, Shuai Zhao, Chenhao Jia +2
Due to the merits of high efficiency and strong security against timing and side-channel attacks, ChaCha has been widely applied in real-time communication and data streaming scena…
