Abstract :
The discrimination of quantum measurements belongs to current topics of quantum information processing. We have experimentally demonstrated one-copy optimal unambiguous (probabilistic) discrimination of two, in general incompatible, von Neumann measurements. To be optimal, this quantum information processing requires pairs of entangled particles and as part of the analyzing protocol conditionally performed unitary operation depending on the measured results on a probe particle.
