Measuring Multipartite Concurrence with a Single Factorizable Observable
Leandro Aolita, Florian Mintert
abstract: We show that, for any composite system with an arbitrary number of
finite-dimensional subsystems, it is possible to directly measure the
multipartite concurrence of pure states by detecting only one single
factorizable observable, provided that two copies of the composite state are
available. This result can be immediately put into practice in trapped-ion and
entangled-photon experiments.
