Quantum metrology in a driven-dissipation down-conversion system beyond the parametric approximation
Dong Xie, Chunling Xu
We investigate quantum metrology in a degenerate down-conversion system composed of a pump mode and two degenerate signal modes. In the conventional parametric approximation, the p…

Quantum metrology in coarsened measurement reference
Dong Xie, Chunling Xu, Anmin Wang
We investigate the role of coarsened measurement reference in quantum metrology. Coarsened measurement reference comes from the coarsened reference time and basis. When the measure…
