Detecting and estimating coherence based on coherence witnesses
Zhao Ma, Zhou Zhang, Yue Dai +2
Quantum coherence has wide-ranging applications from quantum thermodynamics to quantum metrology, quantum channel discrimination and even quantum biology. Thus, detecting and quant…
Interatomic interaction of two ground-state atoms in vacuum: contributions of vacuum fluctuations and radiation reaction
Wenting Zhou, Shijing Cheng, Hongwei Yu
We generalize the formalism proposed by Dalibard, Dupont-Roc and Cohen-Tannoudji [the DDC formalism] to the fourth order of the coupling constant, which can be used to study the in…
Measurement of the mechanical reservoir spectral density in optomechanical system
Wen-Zhao Zhang, Xian-Ting Liang, Jiong Cheng +1
To investigate the dynamical behavior of a quantum system embedded in a memory environment, it is crucial to obtain the knowledge of the reservoir spectral density. However, such k…
Radiation-reaction-induced transitions of two maximally entangled atoms in non-inertial motion
Wenting Zhou, Hongwei Yu
We apply the DDC formalism [proposed by Dalibard, Dupont-Roc and Cohen-Tannoudji] to study the average rate of change of energy of two identical two-level atoms interacting with th…
