Unbounded quantum Fisher information in two-path interferometry with finite photon number
Y. R. Zhang, G. R. Jin, J. P. Cao +2
The minimum error of unbiased parameter estimation is quantified by the quantum Fisher information in accordance to the Cramér-Rao bound. We indicate that only superposed NOON stat…

Phase diffusion of a two-component Bose-Einstein condensates: exact and short-time solutions for arbitrary coherent spin state
G. R. Jin, B. B. Wang, Y. W. Lu
We investigate phase diffusion of a two-component Bose-Einstein condensates prepared initially in arbitrary coherent spin state . Analytical expression of the phas…
