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 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…
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…
