Discrimination of two mixed quantum states with maximum confidence and minimum probability of inconclusive results
Ulrike Herzog
We study an optimized measurement that discriminates two mixed quantum states with maximum confidence for each conclusive result, thereby keeping the overall probability of inconcl…
Optimum unambiguous identification of d unknown pure qudit states
Ulrike Herzog, Janos A. Bergou
We address the problem of unambiguously identifying the state of a probe qudit with the state of one of d reference qudits. The reference states are assumed pure and linearly indep…
Theory of biphoton generation in a single-resonant optical parametric oscillator far below threshold
Ulrike Herzog, Matthias Scholz, Oliver Benson
We present a quantum-theoretical treatment of biphoton generation in single-resonant type-II parametric down-conversion. The nonlinear medium is continuously pumped and is placed i…
Optimum unambiguous discrimination of two mixed states and application to a class of similar states
Ulrike Herzog
We study the measurement for the unambiguous discrimination of two mixed quantum states that are described by density operators and of rank d, the supports of which joi…
