Optimum measurement for unambiguously discriminating two mixed states: General considerations and special cases
Ulrike Herzog, Janos A. Bergou
Based on our previous publication [U. Herzog and J. A. Bergou, Phys.Rev. A 71, 050301(R) (2005)] we investigate the optimum measurement for the unambiguous discrimination of two mi…

Optimal unambiguous filtering of a quantum state: An instance in mixed state discrimination
Janos Bergou, Ulrike Herzog, Mark Hillery
Deterministic discrimination of nonorthogonal states is forbidden by quantum measurement theory. However, if we do not want to succeed all the time, i.e. allow for inconclusive out…

Optimum unambiguous discrimination of two mixed quantum states
Ulrike Herzog, Janos A. Bergou
We investigate generalized measurements, based on positive-operator-valued measures, and von Neumann measurements for the unambiguous discrimination of two mixed quantum states tha…
