Abstract:
One advantage of quantum algorithms over classical computation is the possibility to spread out, process, analyse
and extract information in multipartite configurations in coherent superpositions of classical states. This will be discussed
in terms of quantum state identification problems based on a proper partitioning of mutually orthogonal sets of states. The
question arises whether or not it is possible to encode equibalanced decision problems into quantum systems, so that a single
invocation of a filter used for state discrimination suffices to obtain the result.
