Observables can be tailored to change the entanglement of any pure state
Observables can be tailored to change the entanglement of any pure state
We show that, for a finite-dimensional Hilbert space, there exist observables that induce a tensor product structure such that the entanglement properties of any pure state can be tailored. In particular, we provide an explicit, finite method for constructing observables in an unstructured $d$-dimensional system so that an arbitrary known …
