Quantum Coherence in Reflected and Refracted Beams: A Van Cittert-Zernike Approach
Yuetao Chen, Gaiqing Chen, Jin Wang +3
Recent advances in quantum optics have highlighted the critical role of spatial propagation in controlling the quantum coherence of light beams. However, the evolution of quantum c…
Quantum metrology of hopping strength in a one-dimensional electronic chain
Yuetao Chen, Gaiqing Chen, jin Wang +3
The electron hopping between the two sites in a lattice is of fundamental importance in condensed matter physics. Precise control of the hopping strength allows for the prospect of…
Simultaneous multiple angular displacement estimation precision enhanced by the intramode correlation
Shoukang Chang, Wei Ye, Xuan Rao +5
The angular displacement estimation is one of significant branches of quantum parameter estimation. However, most of the studies have focused on the single-angular displacement est…
High-precision estimation of the parameters in the reservoir via the two-level system
Mengmeng Luo, Wenxiao Liu, Yuetao Chen +1
A scheme is proposed to estimate the system and environmental parameter, the detuning, temperature and the squeezing strength with a high precision by the two-level atom system. It…
