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…

Directed coherent transport due to Bloch oscillation in two dimensions
J. M. Zhang, W. M. Liu
We point out that in higher dimensions, in contrast to the one dimensional case considered usually, Bloch oscillation driven by a static force can induce transport of the wave pack…
