%0 Journal Article %A Luis Aina, Alfredo %T Maximum likelihood state between measurements %D 2009 %@ 1050-2947 %U https://hdl.handle.net/20.500.14352/44645 %X We estimate the quantum state of a system between two measurements via a maximum likelihood strategy. This incorporates all the information provided by preselection and postselection in a legitimate quantum state. Moreover, it allows to include any other constraint derived from practical considerations. %~
