We introduce a protocol that maps finite-dimensional pure input states onto approximately Gaussian states in an iterative procedure. This protocol can be used to distill highly entangled bipartite Gaussian states from a supply of weakly entangled pure Gaussian states. The entire procedure requires only the use of passive optical elements and photon detectors, which solely distinguish between the presence and absence of photons.

Gaussian quantum information (2011, methodology): “…Gaussian LOCC operations (Eisert, Scheel, and Plenio, 2002; Fiuràšek, 2002a;Giedke andCirac, 2002), but canbe achieved using nonGaussian operations that map Gaussian states into Gaussian states (Browne et al., 2003), as recently demonstrated by Takahashi et al. (2010) and Xiang et al. (2010).”
