Dissipative quantum Fisher information for a general Liouvillian parameterized process
Jia-Xin Peng, Baiqiang Zhu, Weiping Zhang +1
The dissipative quantum Fisher information (DQFI) for a dynamic map with a general parameter in an open quantum system is investigated, which can be regarded as an analog of the qu…
Optomechanical preparation of photon number-squeezed states with a pair of thermal reservoirs of opposite temperatures
Baiqiang Zhu, Keye Zhang, Weiping Zhang
Photon number-squeezed states are of significant value in fundamental quantum research and have a wide range of applications in quantum metrology. Most of their preparation mechani…
Preservation Macroscopic Entanglement of Optomechanical Systems in non-Markovian Environment
Jiong Cheng, Wen-Zhao Zhang, Ling Zhou +1
We investigate dynamics of an optomechanical system under the Non-Markovian environment. In the weak optomechanical single-photon coupling regime, we provide an analytical approach…
Nonlinearity enhancement in optomechnical system
Ling Zhou, Jiong Cheng, Yan Han +1
The nonlinearity is an important feature in the field of optomechanics. Employing atomic coherence, we put forward a scheme to enhance the nonlinearity of the cavity optomechanical…
Entanglement of nanomechanical oscillators and two-mode fields induced by atomic coherence
Ling Zhou, Yan Han, Jietai Jing +1
We propose a scheme via three-level cascade atoms to entangle two optomechanical oscillators as well as two-mode fields. We show that two movable mirrors and two-mode fields can be…
