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…
