Device-independent randomness expansion against quantum side information
Wen-Zhao Liu, Ming-Han Li, Sammy Ragy +9
The ability to produce random numbers that are unknown to any outside party is crucial for many applications. Device-independent randomness generation does not require trusted devi…
Realigned Hardy's Paradox
Shuai Zhao, Qing Zhou, Si-Ran Zhao +7
Hardy's paradox provides an all-versus-nothing fashion to directly certify that quantum mechanics cannot be completely described by local realistic theory. However, when considerin…
Field demonstration of distributed quantum sensing without post-selection
Si-Ran Zhao, Yu-Zhe Zhang, Wen-Zhao Liu +12
Distributed quantum sensing can provide quantum-enhanced sensitivity beyond the shot-noise limit (SNL) for sensing spatially distributed parameters. To date, distributed quantum se…
Experimental Quantum Switching for Exponentially Superior Quantum Communication Complexity
Kejin Wei, Nora Tischler, Si-Ran Zhao +13
Finding exponential separation between quantum and classical information tasks is like striking gold in quantum information research. Such an advantage is believed to hold for quan…
Loophole-free test of local realism via Hardy's violation
Si-Ran Zhao, Shuai Zhao, Hai-Hao Dong +5
Bell's theorem states that quantum mechanical description on physical quantity cannot be fully explained by local realistic theories, and lays solid basis for various quantum infor…
Experimental Realization of Device-Independent Quantum Randomness Expansion
Ming-Han Li, Xingjian Zhang, Wen-Zhao Liu +12
Randomness expansion where one generates a longer sequence of random numbers from a short one is viable in quantum mechanics but not allowed classically. Device-independent quantum…
