Phase-sensitive nonclassical properties in quantum metrology with a displaced squeezed vacuum state
Zhiwei Tao, Yichong Ren, Azezigul Abdukirim +2
We predict that the phase-dependent error distribution of locally unentangled quantum states directly affects quantum parameter estimation accuracy. Therefore, we employ the displa…

Physical meaning of the deviation scale under arbitrary turbulence strengths of optical orbital angular momentum
Zhiwei Tao, Yichong Ren, Azezigul Abdukirim +2
The recently so-called deviation scale [C. M. Mabena et al., Phys. Rev. A 99, 013828 (2019)] bridges the connection between the result of the infinitesimal propagation equation (IP…
