Direct Characteristic-Function Tomography of the Quantum States of Quantum Fields
Zehua Tian, Jiliang Jing, Jiangfeng Du
Herein, we propose a novel strategy for implementing a direct readout of the symmetric characteristic function of the quantum states of quantum fields without the involvement of id…
Probing cosmic string spacetime through parameter estimation
Ying Yang, Jiliang Jing, Zehua Tian
Quantum metrology studies the ultimate precision limit of physical quantities by using quantum strategy. In this paper we apply the quantum metrology technologies to the relativist…
Inhibiting decoherence of two-level atom in thermal bath by presence of boundaries
Xiaobao Liu, Zehua Tian, Jieci Wang +1
We study, in the paradigm of open quantum systems, the dynamics of quantum coherence of a static polarizable two-level atom which is coupled with a thermal bath of fluctuating elec…
Relativistic Quantum Metrology in Open System Dynamics
Zehua Tian, Jieci Wang, Heng Fan +1
Quantum metrology studies the ultimate limit of precision in estimating a physical quantity if quantum strategies are exploited. Here we investigate the evolution of a two-level at…
Dynamics and quantum entanglement of two-level atoms in de Sitter spacetime
Zehua Tian, Jiliang Jing
In the framework of open quantum systems, we study the internal dynamics of both freely falling and static two-level atoms interacting with quantized conformally coupled massless s…
Effects of prepared states and Unruh temperature on Measurement-Induced-Nonlocality
Zehua Tian, Jiliang Jing
How the prepared states and Unruh effect affect Measurement-Induced-Nonlocality (MIN) is studied. We show that, as the Unruh temperature increases, the MIN between modes $\mathrm{A…
