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…
Testing Local Realism into the Past without Detection and Locality Loopholes
Ming-Han Li, Cheng Wu, Yanbao Zhang +16
Inspired by the recent remarkable progress in the experimental test of local realism, we report here such a test that achieves an efficiency greater than (78%)^2 for entangled phot…
Device independent quantum random number generation
Yang Liu, Qi Zhao, Ming-Han Li +16
Randomness is critical for many information processing applications, including numerical modeling and cryptography. Device-independent quantum random number generation (DIQRNG) bas…
