Generation of quantum coherence for continuous variables between causally disconnected regions in dilaton spacetime
Qinglong Xiao, Cuihong Wen, Jiliang Jing +1
We study the dynamics of Gaussian quantum coherence under the background of a Garfinkle-Horowitz-Strominger dilaton black hole. It is shown that the dilaton field has evident effec…
Quantum speedup dynamics process in Schwarzschild space-time
Kai Xu, Han-Jie Zhu, Guo-Feng Zhang +2
Quantum speed limit time (QSLT) can be used to characterize the intrinsic minimal time interval for a quantum system evolving from an initial state to a target state. We investigat…
Estimating the Unruh effect via entangled many-body probes
Jieci Wang, Li Zhang, Songbai Chen +1
We study the estimation of parameters in a quantum metrology scheme based on entangled many-body Unruh-DeWitt detectors. It is found that the precision for the estimation of Unruh…
Synchronization and estimation of gravity-induced time difference for quantum clocks
Jieci Wang, Tonghua Liu, Jiliang Jing +1
It has recently been reported [\textit{PNAS} \textbf{114}, 2303 (2017)] that, under an operational definition of time, quantum clocks would get entangled through gravitational effe…
Generation of genuine tripartite entanglement for continuous variables in de Sitter space
Jieci Wang, Cuihong Wen, Songbai Chen +1
We study the distribution of quantum entanglement for continuous variables among causally disconnected open charts in de Sitter space. It is found that genuine tripartite entanglem…
Shadow of a rotating squashed Kaluza-Klein black hole
Fen Long, Jieci Wang, Songbai Chen +1
We study the shadow of a rotating squashed Kaluza-Klein (KK) black hole and the shadow is found to possess distinct properties from those of usual rotating black holes. It is shown…
