Anomalous heat flow and quantum Otto cycle with indefinite causal order
Qing-Feng Xue, Qi Zhang, Xu-Cai Zhuang +5
The principle that heat spontaneously flows from higher temperature to lower temperature is a cornerstone of classical thermodynamics, often assumed to be independent of the sequen…
Experimental Multipartite Entanglement Detection With Minimal-Size Correlations
Dian Wu, Fei Shi, Jia-Cheng Sun +5
Multiparticle entanglement is a valuable resource for quantum technologies, including measurement based quantum computing, quantum secret sharing, and a variety of quantum sensing…
The communication power of indefinite causal order
Xuanqiang Zhao, Benchi Zhao, Cyril Branciard +1
Quantum theory is in principle compatible with scenarios where physical processes occur in an indefinite order, potentially yielding advantages in a broad range of information proc…
Artificial intelligence for representing and characterizing quantum systems
Yuxuan Du, Yan Zhu, Yuan-Hang Zhang +8
Efficient characterization of large-scale quantum systems, especially those produced by quantum analog simulators and megaquop quantum computers, poses a central challenge in quant…
Power and limitations of distributed quantum state purification
Benchi Zhao, Yu-Ao Chen, Xuanqiang Zhao +3
Quantum state purification protocols, which mitigate noise by converting multiple copies of noisy quantum states into fewer copies with a lower noise level, have applications in qu…
A Quantum Superposition of Black Hole Evaporation Histories: Recovering Unitarity
Ali Akil, Lorenzo Giannelli, Leonardo Modesto +3
Black hole evaporation is one of the most striking phenomena at the interface between gravity and quantum physics. In Hawking's semi-classical treatment, where matter is quantum me…
