    • The proof of such properties can be found in Ref. [24] for finite-dimensional Hilbert spaces. Anyway, since the proof essentially relies on the use of the Jordan decomposition, it still holds in infinite dimensions; see also J. Eisert, Ph.D. thesis, University of Potsdam, 2001.

    • 1/4. This constraint can be easily satisfied with the present experimental technology: even for the quite unfavorable case μ=0.5 the squeezing parameter needed is just r≃0.3.
