  We study the change of multiparticle entanglement if one particle becomes
classical, in the sense that this particle is destructed by a measurement, but
the gained information is encoded into a new register. We present an estimation
of this change for different entanglement measures and ways of encoding. We
first simplify the numerical calculation to analyze the change of entanglement
under classicalization in special cases. Second, we provide general upper and
lower bounds on the entanglement change. Third, we show that the entanglement
change caused by classicalization of one qubit only can still be arbitrarily
large. Finally, we discuss cases where no entanglement is left under
classicalization for any possible measurement. Our results shed light on the
storage of quantum resources and help to develop a novel direction in the field
of quantum resource theories.
