Shifting entanglement from states to observables — •Kedar Ranade1 and Nathan Harshman2,1 — 1Institut für Quantenphysik, Universität Ulm, 89069 Ulm — 2Department of Physics, American University, Washington DC
We illustrate that for any pure state on a finite-dimensional Hilbert space we can construct observables that induce a tensor product structure such that the amount of entanglement of the state may take arbitrary values. In particular, we provide an example of how to construct observables on a d-dimensional system such that an arbitrary known pure state can be treated as maximally entangled. In effect, we show how entanglement properties can be shifted from states to observables.
