Modes mismatch induced variation of quantum coherence for two-mode localized Gaussian states in accelerated frame
Xiaolong Gong, Yue Fang, Tonghua Liu +1
Quantum coherence is the basic concept of superposition of quantum states and plays an important role in quantum metrology. We show how a pair of uniformly accelerated observers wi…

What are recent observations telling us in light of improved tests of distance duality relation?
Liu Tonghua, Cao Shuo, Ma Shuai +3
As an exact result required by the Etherington reciprocity theorem, the cosmic distance duality relation (CDDR), plays an essential part in modern…
