Four Generations of Quantum Biomedical Sensors
Xin Jin, Priyam Srivastava, Ronghe Wang +7
Quantum sensing technologies offer transformative potential for ultra-sensitive biomedical sensing, yet their clinical translation remains constrained by classical noise limits and…
Fully-Passive Twin-Field Quantum Key Distribution
Wenyuan Wang, Rong Wang, H. F. Chau +1
We propose a fully passive twin-field quantum key distribution (QKD) setup where basis choice, decoy-state preparation and encoding are all implemented entirely by post-processing…
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…
Secure quantum key distribution against correlated leakage source
Jia-Xuan Li, Yang-Guang Shan, Rong Wang +7
Quantum key distribution (QKD) provides information theoretic security based on quantum mechanics, however, its practical deployment is challenged by imperfections of source device…
One-Shot Min-Entropy Calculation Of Classical-Quantum States And Its Application To Quantum Cryptography
Rong Wang, H. F. Chau
In quantum Shannon theory, various kinds of quantum entropies are used to characterize the capacities of noisy physical systems. Among them, min-entropy and its smooth version attr…
Quantum Discord Witness With Uncharacterized Devices
Rong Wang, Yao Yao, Zhen-Qiang Yin
Quantum discord represents a correlation beyond classicality that could be useful for many quantum information tasks, and therefore is viewed as a valuable quantum resource. Theore…
