Extremality of Gaussian quantum states
Michael M. Wolf, Geza Giedke, J. Ignacio Cirac
We investigate Gaussian quantum states in view of their exceptional role within the space of all continuous variables states. A general method for deriving extremality results is p…

Quantum measurement of a mesoscopic spin ensemble
G. Giedke, J. M. Taylor, D. D'Alessandro +2
We describe a method for precise estimation of the polarization of a mesoscopic spin ensemble by using its coupling to a single two-level system. Our approach requires a minimal nu…
