Symmetrized order describes a classical measurement while nonsymmetrized order corresponds to a quantum detector, e.g., one sensitive to either emission or absorption of photons. We show that both order schemes can be embedded in quantum weak-measurement theory taking into account measurements with memory, characterized by a memory function which is independent of a particular experimental detection scheme. We discuss the resulting quasiprobabilities for different detector temperatures and how their negativity can be tested on the level of second-order correlation functions already. Experimentally, this negativity can be related to the squeezing of the many-body state of the transported electrons in an ac-driven tunnel junction.</dcterms:abstract> <dc:contributor>Bruder, Christoph</dc:contributor> <dcterms:rights rdf:resource=""/> <dcterms:available rdf:datatype="">2013-10-01T10:44:21Z</dcterms:available> <dc:creator>Belzig, Wolfgang</dc:creator> </rdf:Description> </rdf:RDF>
