Gravitational Decoherence Estimation in Optomechanical Systems
Leonardo A. M. Souza, Olimpio P. de Sá Neto, Enrico Russo +2
We develop a comprehensive quantum estimation framework to quantify how precisely gravitationally induced decoherence can be inferred in optomechanical systems, using single-mode G…

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…
